Open Skies Treaty Withdrawal: Unilateral Exit from 35-Nation Arms Control Agreement
Last updated
The Open Skies Treaty allows its 35 signatories — including the United States, Russia, and most NATO and former Warsaw Pact nations — to conduct scheduled unarmed reconnaissance flights over each other's territory. The flights collect imagery that member states share, building collective military transparency. Trump administration officials argued Russia had violated the treaty by restricting U.S. flight paths over certain territories. European allies agreed Russia had compliance issues but argued the U.S. should address them within the treaty framework rather than withdraw, and warned that U.S. withdrawal would give Russia an excuse to exit entirely. Russia did subsequently withdraw from the treaty in January 2021, after Trump's withdrawal had set the precedent. The Biden administration reviewed but did not rejoin the treaty due to concerns about congressional opposition.
Overview
The Open Skies Treaty gave 35 nations — NATO and former adversaries — the ability to fly unarmed surveillance aircraft over each other's territory and share the imagery. For nearly two decades it built military transparency between the United States, Russia, and their allies. Trump withdrew from it in November 2020, citing Russian violations. Russia withdrew in January 2021. The treaty no longer functions.
What the Treaty Did
The concept is straightforward: states are less likely to fear surprise attack if they can see what their neighbors are doing. The Open Skies Treaty formalized mutual aerial inspection as a confidence-building mechanism. Member states could schedule surveillance flights, collect imagery, and share it. The flights were unarmed and subject to strict rules. The transparency they provided was collective — everyone could see.
The treaty was signed in 1992 as the Cold War ended. It entered into force in 2002. It covered 35 states. It worked.
The Withdrawal and the Warning
European allies acknowledged the Russian compliance issues the U.S. cited. They argued the answer was to remain in the treaty, challenge Russia on specific violations, and use the framework to pressure compliance — not to exit and give Russia cover to do the same.
The warning was explicit: U.S. withdrawal would give Russia a pretext to exit and would destroy the treaty's value. Germany, France, and other NATO allies made this case directly to the administration.
The U.S. withdrew on November 22, 2020. Russia announced its withdrawal in January 2021. The treaty was finished.
The Pattern
The Open Skies withdrawal was the fifth major multilateral treaty exit of the Trump administration. The Paris Climate Accord, the Trans-Pacific Partnership, the Iran nuclear deal, and the INF Treaty had all preceded it. Each exit was presented as responding to specific failures of those agreements; each was opposed by allies who argued that remaining and working within frameworks was better than unilateral departure.
The cumulative effect was to raise questions in allied capitals about U.S. reliability as a treaty partner — a concern that would be raised repeatedly throughout the administration.

Trump announces U.S. withdrawal — European allies urge reconsideration
The Trump administration announces the U.S. will withdraw from the Open Skies Treaty, citing Russian violations of flight restrictions over certain territories. European NATO allies immediately urge the U.S. to remain and address violations within the treaty framework rather than exiting.
November 22, 2020
U.S. formally withdraws from Open Skies Treaty
The United States formally withdraws from the Open Skies Treaty six months after announcing its intention to do so. The withdrawal takes effect without a change in Russian compliance with the treaty provisions the U.S. had cited as justification.

Russia announces withdrawal — cites U.S. departure as reason
Russia announces its intention to withdraw from the Open Skies Treaty, citing the U.S. withdrawal as its justification. This is precisely the outcome European allies had warned would result from the U.S. departure. The treaty is effectively gutted with both major military powers outside it.
