The role Turkey can play in NATO’s post-Washington summit aims

The NATO Summit held earlier this month in Washington was a testament to the Alliance’s enduring relevance in upholding shared ideals, values, and common interests as enshrined in the 1949 Washington Treaty. But it also showed that there is still work for NATO and its members to do, particularly in enhancing the Alliance’s collective deterrence and defense in the face of challenges by state and nonstate actors.

NATO has established its place among the most successful political and military alliances in history—despite facing very challenging circumstances since its founding—by dint of solidarity, unity of purpose, and resolve.

Today, allies are presented with challenges such as increasing global systemic rivalry and a complex, interconnected, and unstable security landscape, which threaten Euro-Atlantic security. Russia, as the most significant and direct threat for NATO, has been undermining Euro-Atlantic security since its invasion of Georgia in 2008, and its aggression has since expanded in the form of its invasion of Ukraine. In addition, terrorism—in all forms and manifestations—persists. The topic has been on NATO’s agenda since the adoption of the Alliance’s 1991 Strategic Concept and it (specifically, the 9/11 terror attacks on the United States) was the reason the Alliance decided to invoke Article 5 for the first and only time in history. Since 2001, nonstate actors have continued to lodge a series of terror attacks on a number of allies such as the United Kingdom, Spain, France, and Belgium as well as Turkey, which still grapples with terror attacks from the Islamic State of Iraq and al-Sham and the Kurdistan Workers’ Party (PKK), as well as the latter’s Syrian leg.

NATO allies must maintain their resolve and remain vigilant and ready to face challenges from any direction. Defense is not cheap, and it requires constant attention, care, and investment.

Since joining the Alliance seventy-two years ago, Turkey has contributed to NATO’s security in various theaters of instability and conflicts. Turkey was a bulwark against the Soviet threat in the Cold War period, and it continued to spend significantly on defense, sacrificing the opportunity to spend more elsewhere. For example, Turkey dedicated a level of forces and capabilities NATO in that period that was significant for the Alliance’s security and reduced pressure on allies in Central and Eastern Europe.

Turkey, because it continued to spend on defense, did not benefit from the post-Cold War “peace dividend” to the extent that European NATO allies enjoyed during the early 1990s when the unifying vision to establish a belt of security, stability, and prosperity that included Russia (extending from Vancouver to Vladivostok) was first launched by the United States. During this period, Turkey spent around or above 4 percent of its gross domestic product on defense, while most other allies saw their commitments wane over time.

In the immediate post-Cold War era, Turkey faced challenges from nearby regional conflicts in the Gulf, the Balkans, and the South Caucasus. Yet this conflictual period did not stop Turkey from contributing to NATO efforts designed to protect peace and stability throughout the Euro-Atlantic area and beyond. Turkey actively took part in NATO operations in Bosnia-Herzegovina and Kosovo, and it also made significant contributions to the International Security Assistance Forces in Afghanistan, which was followed by the Resolute Support Mission.

Today, Turkey has similarly consistently supported NATO efforts to enhance peace, stability, and prosperity in the Euro-Atlantic area, even despite divergent perceptions in allied capitals about Turkey’s approach to recent global challenges such as Russia’s war in Ukraine and the war in Gaza.

For example, Turkey did join its NATO allies in approving the most recent NATO Strategic Concept, adopted at Madrid in 2022, that identified Russia and terrorism (along with other regional and global challenges) as threats for the Alliance. Turkey is also set to play a pivotal role in the implementation of regional plans launched at the Vilnius summit last year which are dedicated to the defense of Southern Europe against the pervasive challenges in its immediate vicinity.

Turkey’s role in Washington summit outcomes

With the Russian threat looming over European security, it is high time to strengthen the European pillar of NATO. Allies at the NATO summit acknowledged the need to close the gaps between Europe’s defense needs and its capabilities. This includes, as highlighted at the Washington summit, expanding European allies’ defense manufacturing capacity in a coherent, complementary, and interoperable manner. To achieve interoperability will also require Turkey and NATO to find a lasting solution to the spat over the current Turkish administration’s decision in 2017 to procure the S-400 Russian missile system. While expanding capacity, the allies must take into account both the Alliance’s defense priorities and Ukraine’s needs as it continues to face up against Russian aggression.

Turkey can play a crucial role in helping expand the Alliance’s defense capacity through its contributions to collective deterrence and defense. Capabilities being produced by the growing Turkish defense industry cannot be sidelined in the Alliance’s endeavor to enhance deterrence and defense and maintain a technological edge against both state and nonstate adversaries. This will require result-oriented consultations within NATO and especially between European allies and Turkey, conducted with renewed vigor and mutual resolve. To this end, it is high time for the European Union (EU) to revisit its policies that engage only EU members in enhancing Europe’s defense capacity. Today’s challenges require collaboration with non-EU countries, such as Turkey, to the fullest extent.

With terrorism plaguing Turkey’s neighborhood, and with the issue remaining high on Turkey’s agenda, Ankara likely welcomed allies’ commitment (as outlined in the Washington Summit Declaration) to “counter, deter, defend, and respond to threats and challenges posed by terrorists and terrorist organizations based on a combination of prevention, protection, and denial measures with determination, resolve, and in solidarity.” If allies align their perceptions of the threat to Turkey posed by the PKK and its affiliates by including, for instance, deterrence and defensive measures against the threat in the regional defense plan for Southern Europe, this would help ease the friction on this major issue and help erase the Turkish society’s negative perceptions of NATO allies.

The Washington Summit Declaration also included a reference to the 1936 Montreux Convention. While some Turkish observers have oddly argued the reference is ill-intentioned, it is actually a major outcome for Turkey, as the allies reaffirmed their commitments to “regional efforts aimed at upholding security, safety, stability, and freedom of navigation in the Black Sea region.” The communiqué also welcomed the joint endeavor of three littoral allies (Turkey, Bulgaria, and Romania) to launch the Black Sea Mine Countermeasures Task Group.

Finally, with the global order at stake—due to Russia’s aggression, China’s growing global influence, and threats to security including terrorism—it has become vitally important to maintain and increase cooperation with southern neighborhood countries. The Alliance recognized this importance at the Washington summit, when it committed to taking a new approach toward its “southern neighborhood.” As part of that approach, the NATO secretary general appointed a new special representative for the southern neighborhood to coordinate NATO’s efforts in that neighborhood. Turkey could play a positive role in improving ties between the Alliance and the southern neighborhood by leveraging the linguistic, kinship, religious, and cultural ties it has with other countries. Turkey could also mobilize opportunities that it has in being part of the Organisation of Islamic Cooperation and Organization of Turkic States, and in working with the Gulf Cooperation Council and African Union.

The Alliance has once again proven its relevance and value in protecting and defending the Euro-Atlantic area. As it continues to work to keep the Euro-Atlantic area safe, secure, and stable, Turkey has an important role to play.
