Imagine if Operation Paperclip didn't happen. Well, even if it didn't happen, the scientists and engineers that ended up in America mostly wanted to be there anyway, or at least wanted to and made sure to surrender to the allies rather than the Soviets. 

Anyway, imagine all of those guys didn't end up in America. Imagine Von Braun and his crew were kidnapped by the Soviets. As well as other aero and jet engineers. Where does that go?

Would you rather be (actually) ruled over by a single, soul destroying communist global hegemon run by paranoid, murdering tyrants? I think you may be discounting, and even taking for granted, what America's power projection has done for you and everyone else.
