However, in the Czech case, IIRC, there were no actual Soviet troops on the ground by 1948, they had evacuated the country earlier. I may be wrong on this, but thats what I remember, thinking that for that reason Czechoslovakia had some wiggle room, unlike Hungary, where the mostly non-communist government was trying to get the Soviets out of Hungary, but the Soviets kept coming up with excuses to stay.
You're right, I was just saying that Finland wasn't "liberated" by Soviet troops.
The point is the Allies agreed de facto on a Soviet influence zone based on the advance of Soviet troops.
Even if communists hadn't won 1948 elections, they would have find a way to impose their rule and, eventually, Western countries would have done nothing.
One weird possibility would have been for Moscow to support a break-up between Czech Republic and Slovakia, as the Communists would have had no problem to take power early in Slovakia alone.
It would have reminded of recent Slovak independence, but Stalin didn't bother with "small" contradictions....
Anyway, not very likely, as it would have been seen as a failure in Moscow.
