Prof. Toğrul İsmayıl. Turkey and Israel: Where Is the Red Line, and Is the Mecca Agreement Changing the Regional Balance?

Toğrul İsmayıl - Turkish political scientist, Professor at the Department of Political History, Kahramanmaraş University

Turkish President Recep Tayyip Erdoğan’s statement that Ankara will not back down if Israel decides to attack Turkey should be viewed not as a declaration that war is inevitable, but as a warning that a specific “red line” exists.

Today, a direct military confrontation between Turkey and Israel remains unlikely, but it can no longer be regarded as an entirely hypothetical scenario. The Middle East’s regional security system has changed so substantially in recent months that a localized conflict could very quickly develop into a broader crisis.

This is why Erdoğan’s words should be understood primarily as a signal of deterrence.

Turkey and Israel: How Realistic Is a Direct War?

At present, I would assess the probability of a deliberate full-scale war between Turkey and Israel as low. For both sides, the cost of such a conflict would be extraordinarily high.

Turkey is not interested in a war with Israel. Ankara seeks to preserve room for diplomacy, mediation, and regional influence. Israel, for its part, understands that Turkey is not a state against which a limited military operation can be conducted without serious consequences. Turkey possesses one of NATO’s largest armies, a developed defense-industrial base, powerful naval and air capabilities, and considerable strategic depth.

But the main problem lies elsewhere.

The danger today is not so much a conscious decision by the two states to start a war as it is a possible chain of escalation.

The immediate trigger could be an Israeli strike against Turkish military personnel, diplomatic facilities, or infrastructure that Ankara considers linked to its own security. Particularly dangerous would be the expansion of Israeli military operations into Syria or other neighboring states where Turkish interests are also present.

Another scenario could involve an accidental clash or incident between the armed forces of the two countries. In an environment of highly concentrated military activity, even a limited episode could acquire political significance, after which the leadership of both states could come under pressure to respond.

This is precisely why Erdoğan’s statement should primarily be interpreted as an attempt to prevent war by demonstrating readiness to retaliate.

The logic is classical: if a potential adversary is convinced that the price of an attack will be too high, the likelihood of such an attack decreases.

An Attack on Turkey Would No Longer Be a Bilateral Conflict

The second problem is considerably more serious.

If Israel were to strike Turkish territory directly, it would be virtually impossible to contain the conflict within the framework of a purely Turkish-Israeli confrontation.

The reason is simple: Turkey is a member of NATO.

Article 5 of the Washington Treaty provides that an armed attack against one ally is considered an attack against all. At the same time, it is important to understand that Article 5 does not mean that all allies automatically enter a war. Each ally takes such action as it deems necessary, including, but not necessarily limited to, the use of armed force.

Consequently, an Israeli strike on Turkey would create an unprecedented political situation for NATO: one member of the Alliance would find itself in a direct armed conflict with a state that is not a NATO member but maintains close relations with a number of Alliance countries.

This would become a major test not only for Turkey and Israel but also for the entire Euro-Atlantic security system.

And this raises the central question: could NATO remain on the sidelines?

Formally, yes — if the conflict did not fall under the conditions of collective defense or if the nature of the attack were interpreted differently. But if there were a clear armed attack on Turkish territory, it would be politically extremely difficult to ignore the situation.

Israel must therefore consider not only Turkey’s military capabilities but also the potential consequences for its relations with the United States and European allies.

The Mecca Agreement: A New Deterrence Factor

It is precisely in this context that the agreement between Turkey, Saudi Arabia, and Pakistan, signed in Mecca on August 7, 2026, acquires particular significance.

According to the information made public, the parties agreed to regard an armed attack against one participant as an attack against all. At the same time, the specific mechanisms of military assistance and the scope of commitments have not yet been defined in sufficient detail to describe the arrangement as a full analogue of NATO’s Article 5.

This is a fundamentally important point.

It cannot automatically be claimed that, in the event of an Israeli strike on Turkey, Saudi Arabia would be obliged immediately to deploy its armed forces against Israel or that Pakistan would have to declare war.

International collective-defense agreements function not only through legal formulations but also through political will, existing military mechanisms, the degree of integration between armed forces, and the specific circumstances of an attack.

Nevertheless, it would be a mistake to underestimate the agreement.

Its principal significance lies not in the automatic entry of the three states into a war but in changing the calculations of a potential aggressor.

Israel must now take into account that a strike against Turkey could potentially trigger a chain of political, military, economic, and diplomatic consequences extending far beyond the Turkish-Israeli line of confrontation.

Pakistan is particularly important. It is a nuclear-armed state with a large military and significant combat experience.

Saudi Arabia is no less important, primarily because of its financial capabilities, energy weight, geographical position, and influence in the Arab world.

Turkey, meanwhile, possesses the most developed defense-industrial capacity of the three countries and serves as a link between Europe, the Black Sea, the Caucasus, the Eastern Mediterranean, and the Middle East.

Thus, the agreement creates not so much a “military shield” as a new system of strategic deterrence.

Is a New Military-Political Bloc Emerging?

I would not yet describe this as a fully fledged military-political bloc. It is too early. But we can already speak about the emergence of a new regional security architecture. And that is a fundamental distinction.

Turkey, Saudi Arabia, and Pakistan have different foreign-policy priorities. Their relations with the United States, Iran, Israel, China, and Russia differ considerably.

For this reason, we are not yet dealing with the creation of a “Muslim NATO,” but rather with an attempt by three states to establish a mechanism for collective response amid the weakening of the previous regional security system.

It is highly indicative that Turkey is simultaneously developing consultations with Egypt, Pakistan, and Saudi Arabia. As early as June 2026, the foreign ministers of Turkey, Egypt, Pakistan, and Saudi Arabia discussed collective security and regional stability within the R4 format.

The Mecca Agreement therefore did not emerge from nowhere. It forms part of a longer-term process.

Against Whom Is This Architecture Directed?

Simplification should be avoided here.

It would be incorrect to describe the agreement exclusively as an “anti-Israel bloc.”

Yes, Israeli policy is one of the most important factors that accelerated the creation of a new regional deterrence system, particularly following the expansion of Israeli military operations and rising tensions surrounding Palestine and Jerusalem. Turkey, Saudi Arabia, and Pakistan have repeatedly issued joint statements on the Palestinian issue.

But the agreement has a broader logic.

The second component is Iran.

The region has experienced a period in which Gulf states became directly involved in missile and military confrontation surrounding Iran. For Saudi Arabia, therefore, collective defense is not only about Israel but also about reducing vulnerability to potential missile, drone, and other threats.

The third component is the changing role of the United States.

The paradox is that Washington remains the key external partner of all three states, while these regional powers are simultaneously seeking to reduce their dependence on exclusively American security guarantees.

The Mecca Agreement can therefore be seen as an element of the Middle East’s strategic autonomization.

And this is precisely where its significance extends far beyond Israel.

What Would Happen to NATO?

If we imagine the most severe scenario — a direct Israeli strike on Turkey — NATO would face a situation for which there is virtually no ready-made political template.

Israel is not a NATO member. Turkey is a member of the Alliance.

Therefore, if it were established that Turkey had been subjected to an armed attack, the issue of collective defense would become central.

However, it is important not to go to the opposite extreme.

NATO is not a mechanism that automatically transforms every conflict involving an ally into a common war.

Article 5 leaves allies considerable room to determine what specific actions to take. NATO explicitly states that assistance may include the use of armed force but does not necessarily have to do so.

The most likely initial phase would therefore involve political consultations, an assessment of the nature of the attack, reinforcement of Turkey’s air and missile defenses, intelligence support, an increased military presence, and diplomatic pressure.

But if Israel were to carry out a large-scale strike against Turkish territory and continue military operations, pressure on NATO to take concrete action would rise sharply.

This would create an exceptionally difficult dilemma for the United States.

Washington is simultaneously Israel’s principal military-political partner and the leading power within NATO.

Supporting Israel against Turkey would call into question NATO’s collective-defense principle.

Supporting Turkey would mean entering into a much more complicated confrontation with Israel.

This is why the main deterrent to a direct Turkish-Israeli war may prove to be not only Turkey’s military strength, but also the fear of destroying the existing system of alliances.

Main Conclusion

What we are witnessing today is not preparation for an inevitable Turkish-Israeli war, but rather the formation of a new system of regional deterrence.

Erdoğan is effectively defining a red line: Turkey does not seek war, but it will not accept an attack on its own territory.

At the same time, the Mecca Agreement demonstrates that Turkey is beginning to view its security not only through the prism of NATO but also through the development of regional collective-defense mechanisms.

This is the most important geopolitical trend.

The Middle East is gradually moving away from a model in which security was provided predominantly by external guarantees toward a model of multilayered regional security.

Turkey, Saudi Arabia, and Pakistan have not yet created a new NATO.

But they have taken the first institutional step in that direction.

I would therefore formulate the central conclusion as follows:

Erdoğan is speaking not so much about Turkey’s readiness to start a war with Israel as about the need to make any potential attack on Turkey prohibitively costly for whoever decides to carry it out.

This is the strategic meaning of both Erdoğan’s statement and the Mecca Agreement.

If this system continues to develop, the region will gradually move away from a politics of separate bilateral alliances toward a system of overlapping centers of power. This would amount to a qualitatively new architecture for the Middle East — one in which Turkey seeks to become not merely a regional power, but one of the architects of a new security order.
