Russia on Tuesday formally withdrew from a landmark security treaty which limited key categories of conventional armed forces, blaming the United States for undermining post-Cold War security with the enlargement of the NATO military alliance.
The 1990 Treaty on Conventional Armed Forces in Europe (CFE), signed a year after the fall of the Berlin Wall, placed verifiable limits on categories of conventional military equipment that NATO and the then-Warsaw Pact could deploy.
The treaty was designed to prevent either side of the Cold War from amassing forces for a swift offensive against the other in Europe, but was unpopular in Moscow as it blunted the Soviet Union's advantage in conventional weapons.
