On the insanity that is Iraq

I've written about this before so I'll make this brief but I just don't understand, can't understand the insanity of bombing and blowing up and maiming and killing people in your own country--your fellow countrymen and women (children, too, at times)--for some "purpose" you imagine. Yesterday, there were reports out of Iraq that, now that the US troops have, for the most part, left that country finally, Iraqis are starting to blow up and kill each other again. A headline this week: Iraq bombings kill 60, revive old fears 16 bombs blown across Baghdad alone and 60 people killed. I always assume that it's because of Sunni vs. Shia differences but that just makes it worse, to me. First, it's worse because it's killing for your religion and second, it's far worse because not only are they fellow countrymen you're killing or trying to kill but there are also such small differences, really, between the two religious sects. It is truly insanity. How does a world deal with this kind of mentality? If you can't make it internally, as a nation and a people, how can anyone on the outside of the country help you? And the answer is, of course, they can't.
