Christians and Muslims have lived in peace for many years until we started meddling in their affairs after WW2. There may have been an occasion act of violence but nothing compared to what we have today!
Today's situation in Iraq is about the Shi'a and Sunni. Why the hell would we want to get involved with that?
It is big government interventionist like you that has led to the violence and depletion of our Treasury and loss of thousands of American soldiers and Marines for a failed political Foreign Policy!
The best thing we could do as Americans is to stay they hell out of their business and let them settle their issues. That's because what you advocate has no end to it and is a lose/lose for the USA. The more we kill, the more they bring to arms. Your solution only makes the USA and the world a more dangerous place!
