Was Frank Marshal Davis not a Communist agent? Trevor Loudon's research (found on his website) and his books detail Obama's communist ties extensively.
Those certainly had a role in the destruction of America, but the most destruction came from the hippies and the other protesters
Be specific. Which "protestors" from what organization? Which hippies? The KGB was involved in the anti-war movement and used its front groups to create the "hippies" you are referring to.
As for "warmongers," it sounds like you might be a hippy yourself.
We are in a fight for survival as a free country
Yes, and our enemy is international communism and the ideologies of suicide, such as represented by liberal socialism and Liberaltarian isolationism.
You were doing pretty well with the KGB's destruction of America. No doubt there was more to it than I have read about. However you are falsely equating interventionism and republican free market capitalism (the opposite of liberal socialism). Interventionism clearly undermines free market capitalism. The reason is that economic strength leads to military strength. We can have economic strength and isolationism. Or we can have interventionism which is pot luck. Sometimes it works out such as WWII when we were victorious and benefitted economically. Sometimes it does not like in pissant countries like Vietnam where we were supposed to stop the communist tide. Did that adventure weaken communism in any way? If the politicians had let the military planners run Vietnam do you think we would have won? If your answer to the latter is yes, then I cannot help you. You are a military utopian.
