Also, the U.S. wasn't being invaded by the Red Army, unlike Europe during the first half of the 20th century, so I don't view this as a direct defense of American freedom. Korea and Vietnam were continuations of our meddling in civil wars and regional conflicts, which started with the Great War, a.k.a. World War One.
Well, not every communist government had those characteristics. That aside, yes, I understand that neither those invasions nor the spread of communism came about. So various conflicts that the US were involved in, directly or indirectly (such as Nicaragua) were probably not necessary to defend American dominance (aka 'freedoms'). However, that's with the benefits of hindsight. At the time, many in the administration were convinced about the communist threat (unless you believe Chomsky's argument that the Cold War was about promoting the military-industrial complex). So, although there was plenty of meddling in countries in order to defend US influence, I think it's fair to say that part of the motivation at the time
was a desire to stop the perceived encroachment of communism- and by extension American freedoms. Even though that may have been misguided.
Your zionist moles idea sounds horribly close to a zionist conspiracy idea.
