One thing that I always found strange about the plot is that the Chinese were on our side.
Only because the Soviets killed a few hundred million of them. Thus "on our side" meant that they shared a common enemy.
Today if might be the Russians on our side, after the Chinese invaded Sibera for "living room", and resources.
Heck the Poles, Czechs & Slovaks, Georgians and Ukranians and even the Romanians are on our side, more or less.
