Defeating the USSR isn't to hard as Germany or the USA or even Japan and Italy in Armagedon 1.3. Whats some of the lamest countries you have used to either annex the USSR or fire the bitter peace event? Doesn't have to strictly be by yourself. I managed it with all of the major countries plus Romania who invaded the USSR through Turkey and went into central asia via Stalingrad. Now I'm currently trying it with Manchukuo and its not to easy. If I poull it off it may be a 2-3 year campaign depending on what the German AI does as the USSR DoW themin early 42 and I backstabbed them.
