What accounts for why the soviet union decided to formalize its east european alliance through the warsaw pact? to convince the world that communism was the best choice to pay off a debt to the allies and the empire of japan to create a counter-balance to the nato alliance to threaten the recalcitrant countries of the east

The Soviet Union decided to formalize its East European alliance through the Warsaw Pact as a counter-balance to the NATO alliance. When NATO was formed the Soviet Union saw it as a military threat and also as a threat to Soviet influence in Europe. As a result the Soviet Union decided to build an organization to counter this and formed the Warsaw Pact.
