I suppose. Ron Paul is supportive of Israel, which is fine. He and Rand may present themselves differently, but just as Ron supports Israel he doesn't agree with giving them foreign aid or getting involved with their military operations. Rand said something questionable relating to the military relationship between the US and Israel a couple months ago, but he wouldn't involve the US in an Israeli war. At least he wouldn't be the guy beating the war drums, but if congress were to declare war or authorize military force there's not much he could do as president to cool down the situation. I'm sure he would try.
Gary may be supportive of Israel, but both Ron and Rand would allow Israel to attack Iran and respect their right to defend themselves if they believed they are being threatened. As I understand it, a President Johnson would not just disagree with Israel attacking Iran, but he would actually attempt to stop them somehow.
