"In announcing the intent to withdraw from the Open Skies Treaty, President Trump has doubled down on his short-sighted policy of going it alone and abandoning American leadership. With the world confronting the health and economic consequences of a global pandemic, the United States should be leading the international community, working with allies, and avoiding destabilizing actions.

...The Trump Administration says it is withdrawing from the Treaty because Russia is cheating. There are real concerns that Russia is not complying fully with the Treaty. It has improperly imposed restrictions on overflights over certain regions (Kaliningrad and the Russian-occupied regions of Abkhazia and South Ossetia in Georgia), to which the United States and other parties have objected. These Russian violations should be addressed not by withdrawing from the Treaty, but by seeking to resolve them through the Treaty’s implementation and dispute mechanism. That is exactly how other disputes over Russian implementation have been resolved, including altitude restrictions over Chechnya."

"Even worse than Trump’s contemptible tweeting has been his pro-war policies and actions and his callous disregard for servicemembers. In the last two weeks alone, the Trump administration has... [w]ithdrawn the US from the Open Skies Treaty, which allows its remaining 33 signatories to conduct unarmed surveillance flights over each others’ territories to observe military forces and nuclear weapons installations in order to verify arms control and peace treaty obligations."

"The treaty reduces the chances of international incidents and accidental war, so we should not have withdrawn."
