Explain the u.s. policy of containment during the cold war

I'm not really sure if you need a broad or detailed definition of the policy, but I'm assuming you want a broad explanation.

The US Policy of Containment was a policy put forth during the Cold War to limit the influence of communism around the globe by attempting to prevent the spread of communism from Russia to other countries around the world. Hope that helps :)

Sorry I do not know.
