What is one similarity between NATO and the Warsaw Pact?

The major similarity, then, is that both of these were organizations meant mainly to defend one side against the other. A major difference was that the Warsaw Pact was also created as a way for the Soviet Union to maintain some amount of control over the rest of its bloc. The pact was created soon after Stalin died.
