Aftermath of WW2 With Soviets Attacking Allies in 1945

So let's say Stalin goes nuts again and in May 1945 sends his forces to boot the Allies out of western Germany. The resultant war ends in the latter part of the year with the Americans using atomic weapons to force a capitulation, after Stalin is overthrown. As a result, the Soviet Union soon collapses 1991 style.

So, with this having happened, what happens instead of the Cold War? Where does America go? Where does Europe go? Does China not go communist and so perhaps rise up far faster to fill the great power void? Or does Europe do it, or maybe India, or maybe the U.S. is just totally hegemonic from now on?
 
I've been kicking this idea around for my TL, yet the issue is that the Soviet industry and economy isn't in good shape to start another large-scale war at the time. Not that it isn't possible for the Soviets to do so, just that they can't sustain itself in a protracted struggle against the Allies for the second half of the 1940's.

And as an answer to your questions, the victorious Allies would divide up the former USSR into their spheres of influence; communism discredited all around the world; the USA would still be a world player just more of a hyperpower ala OTL's post-1991; Europe would either slowly become a single nation or just a collection of regional blocs; and the KMT would easily restore its power since Soviet support for the communists would evaporate after the nuclear weapons hit, in fact the KMT-run China would become a rival to the US led world order unless it chooses to cooperate. India would still gain independence since the added cost of war against the USSR would be a bigger strain on the UK so it might get it sooner than OTL.
 
I don't think the Soviets would be able to support a war of attrition against the Allies, considering they've been devastated by 4 years of war against Nazi Germany and sustained millions of casualties in the process. Stalin will be overthrown by Zhukov, Beria or even a coalition of the Soviet Union's top political and military leaders which will most likely attempt to make peace with the Western Allies as the Soviet Union collapses. You'd see many states and peoples declaring their independence from the USSR as it is partitioned into spheres of influence amongst the rest of the Allied Powers, a "Warlord Russia" scenario may emerge in the aftermath. China would remain under the control of the KMT as the Chinese Communists are either crushed or flee into some rump Soviet state in Mongolia, Manchuria and/or Siberia while the KMT reclaims communist-held regions and focuses on rebuilding in the aftermath of ww2. Eastern Europe will remain free instead of becoming communist satellite states but Yugoslavia might remain a socialist federal republic under Tito but the Allies could support a monarchist revolution to overthrow the CPY. You might see a Cold War between the United States and a bloc of European powers attempting to hold onto their colonial empires whose colonial empires may declare themselves independent forcefully but the aforementioned European powers may simply establish a few puppet regimes in Africa and Asia which will be dependent on them. India may become independent faster but I'm not sure.
