The war between Islam and the West has been going on, sometimes fitfully, sometimes full-throttle, for nearly a thousand years. And you can make an argument that the West started it with the Crusades, beginning in 1096.
Imagine the hubris, the arrogance of Obama believing he could stop a thousand-year war with a speech he delivered. I am reminded of Neville Chamberlain talking to Adolf Hitler, then coming home to Britain and announcing "peace in our time."
Rarely is sucking up to one's enemies an appropriate thing to do. When did it ever help?
