NextFin News - Donald Trump is expected to tell Turkish President Recep Tayyip Erdogan that he is prepared to restore Turkey’s access to the F-35 fighter jet program, a significant reversal in a dispute that has shaped U.S.-Turkey defense ties since Ankara was removed in 2019. The reported shift matters not just because the F-35 is the world’s most advanced Western combat aircraft, but because Turkey’s return would require Washington to navigate U.S. sanctions law, congressional skepticism and allied concerns over Ankara’s Russian-made S-400 air-defense system.
The timing is politically sensitive. Trump is expected to meet Erdogan on the sidelines of a NATO summit in Ankara, where defense cooperation, regional security and the future of Turkey’s place in the Western security architecture are all on the table. The F-35 issue is the sharpest symbol of that relationship. Turkey was pushed out of the program after it bought the S-400 from Russia, which U.S. officials said created an unacceptable risk that sensitive information about the aircraft could be exposed to Moscow.
That history is what makes the reported opening remarkable. Turkey’s removal from the program did not just cut off a prospective weapons purchase; it became a broader warning shot about what happens when a NATO member buys a major Russian weapons system. Since then, every discussion about reopening the door to the F-35 has been tied to the same basic obstacle: the S-400 remains in Turkish possession, and U.S. law has treated that as a barrier to arms sales involving the stealth jet.
At the same time, Washington has already signaled a willingness to loosen some defense restrictions on Ankara. Trump’s administration has formally notified Congress of its intention to sell dozens of jet engines worth more than $700 million to Turkey, a move widely read as a confidence-building step between the two governments. That separate proposal does not resolve the F-35 question, but it suggests the White House is willing to use defense trade as leverage while keeping the larger aircraft dispute open.
For Erdogan, the F-35 remains strategically valuable because it would restore a high-end capability that Turkey lost when it was expelled from the program. For Trump, offering progress on the issue gives him a tangible way to reward a partner whose cooperation matters across NATO, the Middle East and Black Sea security. But the same move would also reopen a debate over whether the United States can reconcile a transactional reset with laws written to punish Turkey for the S-400 purchase.
The reported plan therefore goes beyond a single arms sale. It is a test of whether Washington is willing to treat Turkey less as a sanctioned outlier and more as a negotiated partner, even if the underlying problem has not been solved. That tension is what gives the story its importance: the diplomacy may be about jets, but the real stakes are about trust, deterrence and the limits of U.S. leverage.
Why the F-35 Fight Never Really Ended
The central issue is simple: the S-400 purchase changed the logic of the relationship. When Turkey bought the Russian system, U.S. officials argued that allowing it to remain in the F-35 program would risk exposing the aircraft’s classified characteristics to a Russian platform designed to collect air-defense data. That is why the dispute was never merely commercial. It became a national-security problem embedded in alliance politics.
That framework still shapes the debate in 2026. Even if Trump wants to move quickly, Congress retains a role, and the legal and political thresholds are higher than they would be for a routine weapons sale. The issue is not whether Turkey wants the aircraft; it does. The issue is whether Washington can certify that the security risk has been removed in a way that satisfies both U.S. law and skeptical lawmakers.
"We have to certify have happened...in order to comply with American law," Vice President JD Vance said in late June, referring to the review of a possible sale of F-35 fighters to Turkey.
That sentence captures the constraint. The White House can signal openness, but it cannot simply wish away the certification problem. If Turkey keeps the S-400, any effort to restore the F-35 relationship runs into the same question that has haunted the file for years: how can the United States hand over a stealth aircraft to a country still holding a Russian air-defense system that American officials believe can map its capabilities?
The political context also explains why the issue is still alive. Erdogan has spent years trying to balance NATO membership with a more independent defense posture, including deeper ties with Russia and ambitions to build a larger domestic defense industry. That balancing act has produced recurring friction with Washington, but it has not severed the relationship. Instead, the two sides have increasingly treated defense deals as bargaining chips in a broader strategic conversation.
The present moment is different because Trump appears willing to convert that bargaining into a public gesture. If he tells Erdogan he is ready to restore access, that would mark the strongest signal yet that the administration wants a reset rather than a continuation of the freeze. Even so, a signal is not a sale. The legal mechanics, congressional posture and technical security questions would still have to be addressed.
What Washington Gains — And What It Risks
The strongest case for reopening the F-35 door is strategic. Turkey controls critical geography, sits on NATO’s southeastern flank and remains important to U.S. policy in the Black Sea, Syria and the wider Middle East. In that sense, a defense reset could strengthen alliance coordination at a time of elevated regional risk.
There is also an obvious diplomatic upside for Trump. Few gestures would land more visibly with Erdogan than a move toward restoring access to the program from which Turkey was expelled seven years ago. In the language of summit politics, it is the kind of concession that can generate immediate goodwill and create room for other negotiations.
But the risk is that a quick fix could undercut the credibility of the rules the United States used to punish Turkey in the first place. If Washington restores access without resolving the S-400 issue, lawmakers and allies may read the move as a sign that strategic necessity can override security concerns whenever the administration chooses. That could make future arms-control or sanctions policy harder to enforce.
There is also a regional dimension. Israel and Greece have long watched Turkey’s defense buildup with suspicion, and a return to the F-35 program would sharpen those concerns. The aircraft would not merely improve Turkey’s military capabilities; it would alter the balance of advanced air power in a region already defined by overlapping rivalries.
Trump said last week that he would be bringing Erdogan a gift when he arrives in Turkey for the NATO summit, adding that he would probably do something that is going to make him very happy.
That remark now reads like a deliberate hint. But even if the “gift” is an F-35 opening, the real work begins afterward. The administration would still need to define whether Turkey must remove the S-400, place it beyond operational use, transfer it abroad or satisfy some other condition before access can truly be restored. Each of those options carries its own geopolitical and legal complications.
That is why the current report should be read as the start of a negotiation, not the end of one. Trump may want the optics of a breakthrough. Erdogan may want the capability. But the file remains bound by the same unresolved contradiction: the United States wants Turkey closer, yet it still does not trust the Russian hardware that Turkey chose to buy.
The Broader Signal for NATO And U.S.-Turkey Relations
If the White House does move forward, the immediate beneficiary would be Turkey’s government, which could claim it has pushed Washington back toward accommodation after years of punishment. The broader beneficiary could be NATO, if the reset improves coordination with a key member at a time when the alliance faces pressure from Russia, instability in the Middle East and uncertainty over U.S. policy continuity.
But the deeper signal is about how the Trump administration views alliance management. A restoration of F-35 access would show that Washington is willing to trade rigid conditionality for a more flexible, deal-driven approach. That may produce quick wins, but it also raises the question of how durable such wins are if they depend on personal diplomacy rather than structural change.
Turkey’s S-400 problem has not disappeared, and neither has the underlying mistrust around the F-35. That means any announcement in Ankara would likely be only the first chapter in a longer process involving Congress, defense officials and allied consultations. The aircraft is the headline, but the real issue is whether the United States is prepared to rewrite the terms of a security dispute it once treated as settled.
For now, the market-moving fact is the signal itself: Trump appears willing to open the door. The unresolved fact is whether that door can actually stay open without a change in Turkey’s Russian missile posture. Until that question is answered, the F-35 remains less a completed deal than a test of how far diplomacy can bend hard security rules before they break.
