Radical Islam, yes. But the radicals have been a force only recently and that largely as a result of our support of Israel. At the very least, that support has furnished the rallying cry which the radicals use to get the destabilizing mobs into the street. If those mobs succeed in bringing down the moderate Arab governments there will be war to the knife. That is what Saddam (and his buddies) want and that is what the Israel First bunch wants--hence, all the media chatter about those terrible Saudi princes and how awful women have it in Egypt, etc.
