How were the postwar governments and alliances of france different from those of czechoslovakia?

After World War II Czechoslovakia and France had very different governments, being that France embraced a fully capitalist government while Czechoslovakia on the other side, adopted a communist style of government. This had a direct correlation to the alliances they were part of, France along with its capitalist ideas became a member of NATO (as other capitalist nations such as Belgium, Canada, Norway etc.) Meanwhile, Czechoslovakia allied with countries such as Russia and Romania within the Warsaw Pact which was at a union that emerged as kind of a counterbalance of power after the creation of NATO.

both include an amendment process.
