One of the most serious problems in many of these nations is that they do not, or cannot, separate religion and government. One of the wisest things our founding fathers did for us was to establish that difference. Yes, most of our founding fathers did believe in some form of God, in prayer, and often in the Bible, but that's an entirely different thing than religion. Religion takes these common beliefs and tries to make them unique. Of course, the next thing they try to establish is that their religion is "better" than others. Finally, they exercise every option that can be conceived to make everyone else believe the same as they do.
If they can gain political power, those options include laws that declare which religion must be followed. Of course, since they believe that theirs is the only "true" religion, it doesn't matter what anyone else believes. Under these beliefs, there is no contradiction between their cartoons showing Jews and other "unbelievers" in a bad way and their protest of any cartoon that affects them. Since theirs is the only "true" religion, theirs is the only one that can be insulted. They are perfectly within their rights, according to their beliefs, to insult us, or kill us, or anything else they want to do with us, unless we conform to their way of thinking. They see no irony in this. Trying to point it our to them will not work.
This is not unique to Islam. But, it is more or less the standard among most Islamic nations. Sadly, Iraq was one of the exceptions before our invasion; as terrible as he was, Saddam ran a secular government in which the Islamic fundamentalists had little power. What is happening in Iraw right now is that the Shiites have gotten power, and they are intruducing the religious element to the government, similar to the way the Shiites have power in Iran.
I think I'd rather have a nasty dictator who kills off a few of his own people every once in a while, but who can be contained withing his own borders pretty easily, than a radial Isamic government that will try to overcome all others, even by force and terrorism, and is therefore a threat to us. Mark my words, even if Iraq succeeds in becoming a "democracy", as long as the radical Islamics run it, it will be a threat to us. From their point of view, the best thing we are doing is training and equipping their armed forces to be much more effective. When we leave, they'll have a first rate army ready to turn loose on their enemies. Between that and the training and recruitment that our actions are providing for Al Queda, the world is going to be a much more dangerous place.
Then, they'll do more than stomp on flags if they don't like a cartoon...
