Factbox-How Russia-US tensions have undermined key arms treaties

Russia's formal withdrawal from a landmark arms treaty on Tuesday is the latest example of the crumbling of the security architecture that was set up to make the world safer at the end of the Cold War. Arms control pacts in the 1980s and 1990s were a sign of easing tensions and increased trust in East-West relations. Now the opposite is the case: Russia's invasion of Ukraine has brought about the deepest crisis in ties between Moscow and Washington since the 1962 Cuban missile crisis, with the Kremlin describing relations as "below zero".
