It will not. It will only make sure it is the USSR, not Germany, which starts *WW2.
What rubbish. Stalin was
acutely aware of how much weaker the Soviet Union was relative to the Imperialist powers, and how essential a prolonged period of peace was if they were to achieve Socialism in One State; the buildup of the Red Army was to defend against attacks from the West, it wasn't to launch a war of aggression. In addition, with Maxim Litvinov as foreign minister, the Soviet Union was, of all the major powers, the strongest supporters of the International Order and the League of Nations. It was only after the prolonged British and French refusal to stand up to Italian, German and Japanese aggression made it clear that the International Order was doomed anyway that Stalin abandoned the International order and cut a deal with Germany; had the British and French continued to support the League, so too would the Soviet Union.
The Bolsheviks in general,
and Stalin in particular, believed that ultimately war with The West was inevitable, not because the Soviets would begin it, but
because the Capitalist Empires would attack them; Marxist-Leninism held that the Capitalists, upon realising that the Socialist system was superior and would shortly leave them behind industrially, would launch an attack in order to prevent the ultimate success of the Socialist system; consequently the forces of the Revolution needed to always be alert, but would never start the war, since the longer the peace held, the stronger the Soviet Union would be when war finally came.
Historically, after Stalin's death, Khrushchev came to the view that nuclear war would be catastrophic, therefore nuclear war was impossible, and since any war with the West would go nuclear, any war with the west was impossible. Prior to 1960 he believed that ultimately the Socialist system would simply out-produce the capitalists; his widely quoted statement at the reception in Hungary that "
we will bury you" has always been taken completely out of context and is, as a result, seen as a threat; in fact it was a boast; that Soviet industry would soon reach such levels of production that the Capitalists would be
buried under the mountains of manufactured goods that would be produced. After 1960 Khrushchev began to have deep doubts about the Marist-Leninist system, but kept seeking a magic panacea that would solve all of the economic problems, always refusing to accept that insolvency is built into Marxist-Leninism; one of the most essential panaceas to him a was peaceful coexistence with the West that would let him reduce the Soviet Union's defence expenditure to a manageable level. The key point is that after Lenin's demise none of the Soviet leaders ever considered launching a war against the West.
