Like, er, George Washington? Read his farewell speech to Congress and get back to me. I love our military,(I am headed down to Bragg on the 27th to see a dear friend of mine graduate from Special Forces school), but we have no business getting them involved in half the crap we do. They are best to work justice and retribution, smash em up, and say "we will be back for more if you don't behave yourselves and do what we do.... LEAVE US ALONE!" Empire maintainers are hated, despised, attacked at every opportunity, and ultimately blamed for the cowardice and foolishness of their political leaders.
Ron Paul believes we should mind our own business, and he believes the US Government should actually PAY ATTENTION to the limits proscribed for it by the Constitution. I find it difficult to argue with that.
I've never been a fan of isolationism. We "minded our own business" for too long, and that got too many people killed.
