Just had another idea based on the Soviet Union winning non-nuclear WWIII thread: WI during the Cuban Missile Crisis, the Soviets, in response to the US blockade of Cuba- and as speculated in 13 DAYS- began blockading West Berlin ? How much would the ante have been upped during the crisis, and what set of specific circumstances could have facilitated Khrushchev ordering the Red Army to try the 1948-49 Berlin Blockade all over again on a larger scale ?
