The Istanbul Initiative and Red Sea Security: The Dilemma of De-escalation and Yemeni Sovereignty

At a regional moment characterized by overlapping crises and multiple sources of tension, diplomatic initiatives acquire significance that extends beyond the formal statements issued at their conclusion. They raise broader questions about the security arrangements that regional and international powers seek to establish and the limits of possible consensus among their competing interests. In this context, the meeting held in Istanbul on 23 October between the foreign ministers of Türkiye, Egypt, Pakistan, and Saudi Arabia and their counterparts from France, Germany, Italy, and the United Kingdom reflected a growing effort to intensify consultations on regional security, maritime routes, and the risks of military escalation.

The meeting took place amid political sensitivities associated with electoral developments in Israel and the United States, mounting concerns over renewed US and Israeli strikes against Iran, and growing anxiety about the security of maritime routes and supply chains. It also coincided with heightened concerns over Houthi attacks on Saudi Arabia. Against this backdrop, the joint communiqué emphasized dialogue, diplomacy, and de-escalation; condemned Houthi attacks against Saudi Arabia and the Yemeni government; underscored the importance of safe and free navigation through the Strait of Hormuz, Bab el-Mandeb, and the Black Sea; and called for negotiated, lasting solutions. The participants also agreed to continue dialogue in this format.

The political significance of this initiative, however, cannot be determined solely by the participants’ agreement on general principles. It depends on whether the process can move beyond managing tensions toward addressing their underlying causes, and beyond preventing a military confrontation toward establishing more sustainable security arrangements. This raises a fundamental question: does the Istanbul initiative represent an entry point for regional and international coordination capable of reducing the risk of war, or could it become, if limited to partial settlements, a framework for redistributing security burdens without addressing the roots of conflict?

De-escalation Diplomacy and the Problem of Partial Settlements

The Istanbul meeting reflects a growing recognition that an expansion of regional confrontation could impose costs extending far beyond the parties directly involved. Escalation between the United States and Israel on one side and Iran on the other would affect not only military installations or the nuclear file, but also energy security, international trade, transportation and insurance costs, and the ability of states to protect their economic and strategic interests.

From this perspective, diplomacy is an essential instrument for containing risks, particularly given the multiplicity of conflict theatres and the possibility that confrontation could spread from one arena to another. Germany, France, and the United Kingdom’s willingness to negotiate with Iran over preventing it from acquiring a nuclear weapon also reflects the continued European commitment to diplomatic solutions in addressing one of the most sensitive issues in the regional order.

Yet the success of diplomacy cannot be measured merely by whether an understanding is reached that temporarily halts escalation. It must also be assessed in terms of its ability to address the factors that could lead to renewed conflict. A settlement focused exclusively on the nuclear file, without addressing threats to maritime navigation or the use of Iran-aligned armed groups in regional conflicts, might reduce tensions along one track while leaving risks on other tracks unresolved.

It is essential, in this context, to distinguish between established facts and possible scenarios. The communiqué issued after the Istanbul meeting does not establish that an agreement has been reached on enriched uranium, sanctions relief, or Yemen. Proposals concerning the future of Iran’s enriched-uranium stock, including the possibility of transferring it to Russia, remain part of an evolving diplomatic debate and should not be treated as finalized arrangements.

Nevertheless, the possibility of parallel settlements involving the nuclear issue, regional security, and armed conflicts raises a legitimate strategic question: can Iran’s nuclear file be separated from its other instruments of regional influence, or does the durability of any understanding require a broader approach to the sources of mutual threat?

The importance of this question lies in the fact that partial settlements may deliver immediate gains while leaving fundamental issues unresolved, making the resulting stability fragile and vulnerable to reversal. The challenge, therefore, is not whether negotiations should be rejected, but how their scope should be defined, how compliance should be verified, and what guarantees can prevent a temporary lull from being used to rebuild capabilities that could lead to renewed confrontation.

Preventing War and the Risk of Entrenching the Status Quo

Calls for de-escalation do not necessarily imply leniency toward sources of threat, just as negotiations do not inherently constitute a political concession. The problem emerges when avoiding military confrontation becomes an objective detached from addressing the conditions that produced the tension, or when a settlement consolidates arrangements established through the use of force.

Historical experiences with settlements that failed to address the roots of conflict offer useful lessons, provided that the past is not mechanically projected onto the present. Comparisons between contemporary policies and European appeasement in the 1930s are necessarily limited by the historical and political differences between the cases. Nevertheless, a general lesson can be drawn: a settlement is unlikely to produce lasting stability if it disregards the interests of affected parties or leaves the sources of coercion intact without effective monitoring or verifiable constraints.

In the current context, any understanding with Iran should be assessed according to practical criteria, including compliance with nuclear commitments, respect for the sovereignty of neighbouring states, the reduction of threats to international navigation, and the existence of reliable mechanisms for monitoring implementation and responding to violations. Equally important is the extent to which an agreement can reduce the risk of escalation in conflict theatres linked to regional competition.

However, expanding negotiations to encompass every regional issue may itself encounter significant obstacles, as the parties involved differ in their definitions of threats and their conceptions of national security. A more practical approach may therefore involve building gradual, interconnected arrangements that clearly define obligations, allow for their verification, and link progress in de-escalation to concrete measures, without assuming that an understanding on one issue will automatically resolve the others.

Yemen in the Regional Equation—Mentioned in the Communiqué but Absent from the Negotiating Table

The Yemeni file stands out as one of the most important practical tests of the diplomatic process initiated in Istanbul. The joint communiqué condemned Houthi attacks against Saudi Arabia and the Yemeni government, thereby acknowledging the direct relationship between Saudi security and stability in Yemen. Yet the Yemeni government was not among the eight states participating in the meeting.

This highlights a political gap between recognizing a state's interests in diplomatic statements and ensuring its actual participation in shaping arrangements that affect its security, sovereignty, and political future. Yemen is not merely an arena in which Saudi and Iranian interests intersect, nor should its crisis be reduced to a bilateral security equation between Riyadh and the Houthis. It is a sovereign state with a recognized government and national interests directly connected to its territory, coastline, territorial waters, and institutional future.

This issue becomes even more significant if the Istanbul meeting develops into a regular dialogue on regional security. Continued consultations between regional and European powers could facilitate understandings on the security of the Red Sea and Bab el-Mandeb. However, such a process would remain incomplete if it failed to ensure meaningful Yemeni participation in decisions concerning maritime routes and the country's western coastline.

Yemeni participation is not merely a matter of diplomatic protocol. It reflects a fundamental political principle: sustainable security arrangements for a state cannot be established without involving its legitimate institutions in defining priorities and obligations. Excluding Yemen, or treating it as a subordinate issue within regional understandings, could produce solutions that temporarily reduce external risks while leaving unresolved the crisis of authority and the proliferation of armed power within the country.

Accordingly, incorporating the Yemeni government into any future dialogue on maritime security should be regarded as a condition for strengthening the legitimacy of proposed arrangements, rather than as an additional political demand.

The Western Coast and Bab el-Mandeb—From Geography to Strategic Influence

Yemen’s western coastline is one of the principal points at which domestic conflict intersects with regional and international security. Yemen’s location along the Red Sea and its proximity to a major maritime passage connecting the Red Sea with the Gulf of Aden and the Indian Ocean give control over its coastline, ports, and surrounding areas implications that extend beyond the boundaries of the Yemeni conflict.

Bab el-Mandeb is important because it forms part of an interconnected network supporting international trade, energy transportation, and maritime communications. Sustained disruption in this passage can increase shipping and insurance costs, expose commercial vessels to greater risks, and prompt companies and governments to reconsider supply routes. Maritime security consequently becomes more than a narrowly defined naval concern: it becomes a factor affecting international economic and strategic stability.

In this context, one possible scenario is that a US-Iranian understanding could coincide with a parallel de-escalation process between Saudi Arabia and the Houthis. Such a development might halt attacks for a period while leaving the balance of territorial control, particularly across parts of Yemen’s western coastline, largely unchanged. It is important to emphasize that this is an analytical scenario, not evidence of an existing agreement among the parties concerning the future of territorial control in Yemen.

The central concern is that a cessation of attacks, although important from humanitarian and security perspectives, does not necessarily eliminate the sources of threat. If military capabilities and illicit supply and financing networks remain intact, a ceasefire may freeze the conflict rather than create a pathway toward its resolution.

At the same time, restoring state authority along the western coast should not be pursued in isolation from humanitarian and economic considerations. Strengthening oversight of maritime entry points should focus on preventing arms smuggling, disrupting illicit military supply chains, and restricting networks that finance violence, while preserving the flow of humanitarian assistance and lawful commerce. Any approach that fails to distinguish between illicit activities and legitimate civilian movement could deepen public suffering and undermine the prospects for stability.

Addressing the crisis along the western coast therefore requires an integrated approach combining the restoration of state institutions, the development of legitimate security capabilities, effective monitoring of ports and coastal areas, and improvements in economic and humanitarian conditions. Maritime security cannot be guaranteed over the long term through military measures alone, nor can it be separated from the nature of the authority exercising control over the coastline and its ability to fulfil its sovereign responsibilities.

The Limits of Regional Support and the Dilemma of External Dependence

Discussions concerning the security of Saudi Arabia and Yemen reveal a broader issue: the limits of regional support and the difference between political solidarity and a practical commitment to sharing security burdens. Turkish statements have referred to the possibility of supporting Saudi Arabia in a deterrence framework while ruling out direct military involvement against the Houthis.

These statements illustrate that political positions do not necessarily translate into a collective defence commitment, a joint operational plan, or an agreement on the circumstances under which force might be used. States may agree on the importance of protecting maritime navigation while differing over the appropriate means, the risks they are prepared to assume, and the political and military costs of intervention.

For Yemen, complete dependence on external powers to protect its coastline and maritime approaches could create a gap between declared interests and actual capabilities. Even when international actors are willing to protect maritime navigation, sustainable security ultimately depends on national institutions capable of managing ports, monitoring territorial waters, combating smuggling, and enforcing the law.

This does not diminish the importance of international cooperation. Such cooperation may be necessary to provide intelligence, training, technology, and maritime capabilities that a country experiencing a prolonged conflict cannot easily develop on its own. However, cooperation is more effective when it strengthens state institutions rather than replacing them, and when it supports the development of sustainable national capacity instead of creating temporary security arrangements dependent on changing external priorities.

The challenge, therefore, is to build a security partnership that balances external assistance with national responsibility and ensures that the protection of maritime routes does not become a pretext for bypassing Yemeni sovereignty or postponing efforts to address the internal weaknesses that sustain the conflict.

Maritime Security in an Era of Strategic Interdependence

Maritime security is no longer confined to protecting oil tankers and commercial vessels. It has become part of a broader system encompassing digital infrastructure, undersea communication cables, energy networks, ports, and global supply chains. Disruption to maritime routes can therefore affect trade, communications, and data flows, rather than the movement of goods alone.

This interconnectedness requires states to reconsider the concept of maritime security. Rather than focusing exclusively on responding to attacks after they occur, they must also strengthen resilience, diversify routes, develop alternative logistical options, and improve cooperation to protect critical infrastructure. Diversifying transportation and communication routes can reduce excessive dependence on a single passage and limit the ability of any actor to use geographical position as an instrument of political pressure.

In this context, proposals for developing land-based connections and alternative corridors, including initiatives referred to as the ASTRA vision, merit consideration within a broader framework for regional transportation and trade networks. Assessing these proposals, however, requires examining their economic viability, costs, security requirements, and feasibility, as well as their implications for the countries and communities through which they pass.

Most importantly, the development of alternative routes cannot substitute for addressing the roots of Yemen’s crisis or restoring the state's capacity to administer its coastline. Diversifying maritime and land corridors may reduce certain commercial risks, but it cannot resolve the political and security problems that arise when a strategically important coastal area falls outside the effective control of national institutions.

Toward an Integrated Security Approach Linking De-escalation with Sovereignty

The developments surrounding the Istanbul meeting highlight the need to move beyond viewing de-escalation as an isolated objective and instead treat it as one stage in a broader process of building regional security. This requires linking political restraint to verifiable commitments, maritime protection to respect for sovereignty, and temporary security arrangements to the restoration of state institutions.

Such an approach could rest on several interconnected principles.

First, clear criteria should be established for ending attacks against states and international maritime traffic, supported by independent and credible verification mechanisms and defined procedures for responding to violations.

Second, the Yemeni government should be institutionally included in any consultations concerning the security of the Red Sea, Bab el-Mandeb, and the western coastline, ensuring that Yemeni interests are represented in the formulation of regional arrangements.

Third, support should be directed toward strengthening Yemeni state institutions and restoring their security and military functions, including their ability to administer ports and coastlines and combat smuggling, while taking humanitarian needs and lawful commerce into account.

Fourth, Yemen’s crisis should not be reduced to its maritime dimension or to competition among regional powers. It must also be addressed as a crisis of state authority, political legitimacy, and the state's capacity to exercise its legitimate monopoly over the use of force. This requires a broader political settlement.

Fifth, regional understandings should be linked to measurable outcomes rather than general declarations in support of dialogue and peace. Relevant indicators could include a reduction in attacks, improved maritime security, the interruption of illicit arms flows, and greater Yemeni participation in maritime security arrangements.

Sixth, international cooperation should be developed to protect critical maritime and digital infrastructure and diversify trade and supply routes, while ensuring that alternative economic arrangements do not circumvent the states concerned or marginalize their sovereign interests.

These principles do not assume that military action is the only means of achieving stability, nor do they suggest that political agreements alone can address security risks without effective implementation arrangements. Rather, they rest on the proposition that diplomacy becomes more effective when it is supported by specific commitments, institutional capabilities, monitoring mechanisms, and a clear distribution of responsibilities.

Conclusion

The Istanbul meeting indicates a growing need for consultation between regional and European powers on issues that extend beyond national borders, from Iran’s nuclear programme to energy security, maritime navigation, and Yemen’s future. The significance of this initiative, however, should not be measured solely by the participants’ agreement on dialogue and de-escalation. It should be assessed according to its ability to produce practical arrangements that reduce sources of threat and prevent crises from spreading from one arena to another.

Yemen remains a critical test in this regard. Condemning Houthi attacks and acknowledging the importance of maritime security constitute significant political positions. Yet they cannot replace the inclusion of the Yemeni government in decisions affecting its coastline and territorial waters, nor can they compensate for the failure to address the institutional weaknesses that prevent the state from exercising its sovereign functions.

Similarly, any potential understanding concerning Iran’s nuclear programme should be evaluated on the basis of its actual terms, implementation mechanisms, and regional consequences, rather than assumptions about undisclosed agreements. Negotiations may create opportunities to reduce risks, but they cannot by themselves guarantee sustainable stability unless commitments are accompanied by verifiable measures and a realistic response to the sources of tension.

Ultimately, the central dilemma is not whether to choose war or peace, but what kind of peace is to be established: a temporary de-escalation that leaves the instruments of pressure and conflict intact, or a gradual process that addresses threats, strengthens state institutions, and protects the legitimate interests of the states concerned?

The success of the Istanbul initiative will depend on its ability to translate dialogue into practical commitments and to ensure that regional security arrangements do not become bargains negotiated by major and regional powers while the states most directly affected remain outside the decision-making process.

The security of Bab el-Mandeb cannot be separated from Yemeni sovereignty, and lasting stability in the Red Sea cannot be achieved without addressing the causes of conflict along its shores. Any de-escalation process that fails to place this relationship at the centre of its calculations may postpone the crisis, but it cannot guarantee its resolution.
