Alexei Kosygin
Early during Kosygin's tenure, the Brezhnev–Kosygin attempt to create stability was failing on various fronts. From 1969 to 1970, discontent within the Soviet leadership had grown to such an extent that some started to doubt both former and current Soviet policies. Examples include the handling of the Prague Spring and the later Soviet invasion of Czechoslovakia[29] (which Kosygin initially resisted), the decline in agriculture production, the Sino–Soviet border conflict (he advocated restraint), the Vietnam War, and the Soviet–American talks on the limitation of strategic missiles. Two summit conferences between the US and the USSR were held: the Warsaw Pact Summit Conference and the Moscow Summit Conference; both failed to gain support for Soviet policies.
