What if the Soviet Union joined NATO in 1955?

This may be more likely by delaying the Soviet application to Jan 1955, this means the West have seen Kruschev’s De-Stalinisation, Churchill is still in power(who backed Soviet participation in NATO) and West Germany hasn’t entered NATO. This would broadly mean NATO as an anti-communist alliance is destroyed, the Warsaw Pact is likely not created and instead integrated into NATO and Germany unifying and becoming neutral like Austria is likely. Where does the Cold War go from here?
