The guy is a kook. He criticizes Israel for defending themselves, criticizes America for trading with Israel, and then compares palistinain terrorists to concentration camp victims.
Your inability to comprehend complex positions does not make those positions insane.
Paul believes Israel is undermining our international free trade ability, and sucking up too much tax money for what we get back. I'm not taking a position on these specifics - I'm only pointing out that Paul pounds on the enormous power of free trade (which America supposedly stands for) to defuse international war scenarios. It's a good point, and it's sick that more conservatives don't acknowledge it. And Paul isn't against military power - he just believes it will be needed far, far less if we maintain international dominancy through trade.
In fact, his position is so rational that RINOs can only bleat Leftist-styled personal insults at him in response, because they can't fault his logic. Especially on Free Republic, watching such endless kneejerk Paul-abuse is pathetic.
