Erm the West joined the USSR in the end - hmmmmmm me thinks someone is
a - a troll
b - lacking some basic history
c - a soviet version of a wehrberoo
The poor old Soviets carved up eastern Europe with the Nazis in 1939 (Poland, Baltic States), did a deal over Romania pretty much forcing Romania to join the Axis camp, attacked Finland and then sat out of the war watching the Axis and British Commonwealth (along with what forces escaped to continue fighting after their countries were occupied) fight each other - all the while happily supplying Germany with materiel enabling it to prosecute its war (literally upto the minute Germany decided to head East with its allies).
The Soviets only joined in fighting against the Axis when the Axis attacked them
You may not have noticed that the British Commonwealth were fighting looooooong before the Soviets against the Axis - and along with the US supplied huge amounts of equipment to the Soviets al the while fighting all over the world not just along one front (as well as bombing the Axis heavily and supplying the various resistance and partisan groups).
I never realised the rest of the allies never destroyed the Luftwaffe or Kreigsmarine as effective forces, took Italy out of the war, disrupted german war production, kept nearly a million people in AA defence of Germany (with all those guns and ammunition), that the Soviets supplied everything they needed themselves.
