The United States will pull out of the Open Skies Treaty—an arms control pact—with Russia, according to the Department of State on Nov. 22.
"Six months having elapsed, the U.S. withdrawal took effect on November 22, 2020, and the United States is no longer a State Party to the Treaty on Open Skies."
The Open Skies Treaty is an agreement to allow nations to carry out reconnaissance flyovers to obtain military data and intelligence. For years, the United States has accused Russia of violating the terms of the agreement, not allowing the flights over Russian territory.
President Donald Trump earlier this year said he wanted to leave the agreement, which was signed following the end of the Cold War. It came as Trump and administration officials stated that they've been tougher on the Kremlin than previous administrations.
"While the United States, along with our Allies and partners that are States Parties to the treaty, have lived up to our commitments and obligations under the treaty, Russia has flagrantly and continuously violated the treaty in various ways for years," Secretary of State Mike Pompeo said in May.
"This is not a story exclusive to just the treaty on Open Skies, unfortunately, for Russia has been a serial violator of many of its arms control obligations and commitments."
Earlier this summer, the Department of Defense (DOD) said it wasn't in the best interest of the United States to partake in the accord any longer.
The Treaty on Open Skies was first proposed by President Dwight Eisenhower in 1955, but the Soviet Union refused to take part. President George H.W. Bush again suggested the treaty, and in 1992, after the collapse of the Soviet Union, negotiations started. About three dozen nations have taken part after it went into effect in 2002.
