Question

How was the postwar government of France different from that of Czechoslovakia? Which country belonged to NATO? Which was a member of the Warsaw Pact?

Answer 1

France, a NATO country, had a democratic government. Czechoslovakia, a member of the Warsaw Pact, had a communist government. (Apex)

Answer 2

I understand the "postwar" here to mean "after WW2".
After this war, France was capitalist, while Czechoslovakia found itself in the socialist camp, lead by the Soviet Union. Connected to this is the fact that France, like many other capitalist states was member of NATO and Czechoslovakia of the Warsaw Pact.
