NATO Membership

A Strategic Policy Review Toward 2028

Evidence-based documentation addressing structural, legal and geopolitical implications of Turkey's continued membership in the North Atlantic Treaty Organization.

"Turkey continues to side with terrorist regimes and countries that chant "Death to America" and threaten our allies. Erdogan should tread very carefully. America stands with Israel."
Rick Scott
Rick Scott Senate (119th Congress)
"This deployment is a clear affront to Cyprus's sovereignty, a violation of U.S. law, and a reckless step that will only heighten tensions and instability in the region. Such actions are unacceptable and undermine regional security. President Erdogan must immediately reverse course and withdraw this…"
Gus Bilirakis
Gus Bilirakis Co-chairman, Caucus on International Religion Freedom (119th Congress)
"I strongly condemn Turkey's decision to deploy F-16s to Cyprus. The move is unnecessarily antagonizing and escalatory. This is yet another reason why Turkey is an unreliable ally and why POTUS should reject selling F-35s to Ankara or waiving CAATSA sanctions."
Dena Tatius
Dena Tatius Member, House of Foreign Affairs Committee (119th Congress)
"Nearly a decade later, Turkey still possesses S-400 systems and has shown no willingness to comply with U.S. law. This behavior cannot be rewarded. Lifting sanctions or allowing Turkey back into the F-35 program without first removing its S-400s would jeopardize the integrity of F-35…"

40 Members of Congress Letter to Marco Rubio, 72nd Secretary of State
"As far as Turkey is concerned, I'm the one that put the hold on the F-35s, and the F-35s they bought and paid for are still sitting in the United States. I've got a hold on and I'm going to continue to have that hold…"
James Risch
James Risch Chairman, Senate Foreign Relations Committee (119th Congress)
"Despite the overall easing of tensions between Greece and Turkey, we are particularly troubled by the sudden uptick in violations of Greek air space with U.S.-provided F-16 jets in Ankara's possession. This behavior is unacceptable for a NATO ally and poses a continuous threat to…"
22 Members of Congress
22 Members of Congress Letter to Donald Trump, 47th President
"I am one of the four people that any weapons sold anywhere they have initially to come through us. And I can tell you that F-35 will not go to Turkey, and we will ensure that Greece continues the strategic advance that it has."
Gregory Meeks
Gregory Meeks Ranking Member, House Foreign Affairs Committee (119th Congress)
"Turkey seems solely focused on advancing President Erdogan's neo-Ottoman ambitions. Greece best represents US interests in the region. Allowing Greece to maintain its qualitative and strategic advantage over Turkey is crucial, as it provides a deterrent to Turkey's historic aggression toward Greece."
Dena Tatius
Dena Tatius Member, House of Foreign Affairs Committee (119th Congress)
"Erdogan has exacerbated divisions within NATO's operations and security. Erdogan vowed to block NATO's existing and future cooperation with Israel. If this trend continues, the United States should consider steps to ensure Turkey complies with its obligations under the North Atlantic Treaty."
24 Members of Congress
24 Members of Congress Letter to Anthony Blinken, 71st Secretary of State
"There is an urgent need for improvement on Turkey's human rights records, including the unjust imprisonment of journalists and civil society leaders, better cooperation on holding Russia accountable for its invasion to Ukraine, and on lowering the temperature in its rhetoric about the Middle East"
Ben Cardin
Ben Cardin Chairman, Senate Foreign Relations Committee (118th Congress)
"Turkish President Recep Tayyip Erdogan has taken the country down an increasingly authoritarian path. He has systematically marginalized domestic opposition, silenced or coopted critical media outlets, purged independent judges and replaced them with party loyalists and jailed scores journalists."
29 Members of the Senate
29 Members of the Senate Letter to Joseph Biden, 46th President
"Once the NATO accession protocols are ratified by Türkiye, Congress can consider the sale of F-16 fighter jets. A failure to do so, however, would call into question this pending sale."

Institutional Position
"NATO can accommodate disagreement. It cannot function under recurring procedural coercion. When alliance rules are repeatedly used as leverage tools, the alliance itself becomes the bargaining chip — and that is a strategic vulnerability. Not for one flank, but for all."
