"I think we can reactivate [the] Open Skies [Treaty] very quickly... The Trump administration's announcement that it would withdraw from Open Skies is a violation of US law," Stoffer said.
Stoffer explained the law, dubbed the National Defense Authorization Act for 2020, required the Trump administration to notify Congress 120 days ahead of submitting a notification of its intent to withdraw from the treaty.
"The Trump administration never did that. I don't think it even gave a notification until just a short while before when the whole world knew that the United States was going to pull out," Stoffer said.
The United States' participation in the Open Skies Treaty ended in November, six months after the former Trump administration announced its intention to withdraw from the accord. Stoffer said current President Joe Biden should regard the United States’ withdrawal from the Open Skies Treaty as illegal and inappropriate, and Washington should observe the accord in the hope that Russia and the other parties to the treaty will accept the fact that the United States is back.
Moreover, Stoffer emphasized that the Open Skies Treaty is one of the urgent matters the United States and Russia should address, noting that it took many years for the agreement to be concluded.

Last week, Russian Deputy Foreign Minister Sergey Ryabkov said Russia would consider returning to the Open Skies Treaty if the United States reversed its decision to withdraw, but without any concessions.
Ryabkov also said Russia has kept fulfilling the Open Skies Treaty in good faith despite the launch of the withdrawal procedure and is ready to host observer missions.
On January 15, the Russian Foreign Ministry announced Moscow was initiating the procedures to leave the Open Skies Treaty over the disruption of balance of interests after the United States withdrew from the accord. However, Moscow said it would reverse the decision if the European treaty members agree not to share intelligence with the United States on its military infrastructure that was collected during flights as well as allow Russian flights over US military infrastructure located in Europe.
The Open Skies Treaty was signed in 1992 and went into effect ten years later. It allows 34 participating countries to conduct unarmed observation flights over each other's territories.
