Paul’s position is that the wisdom of our “no-entangling alliances” founders is what should “set” (guide) our foreign policy. That way we don’t MAKE enemies for you to talk twistingly about.
I think even more than our killing of their people, the Arabs object to us trying to impose OUR values, OUR culture, OUR institutions, and OUR style of government on them. That’s why I think it is misleading to call it the War In Iraq. The honest name for it would be the War On Iraq.
