I've been thinking this way recently but more specifically toward Islam (surprise). Since more than three quarters of the world is not Muslim we should all demand that parts of the Koran be changed, outlawed and of course no longer taught.
I really think the only way to stop terrorism though is if we had a real asshole of a POTUS who would politely explain to the Islam world that if there is another organized terrorist attack anywhere in the world X city would disappear from the map. The city could rotate. One month we could announce the nukes are aimed at Tehran, the next month it could be Kabul. A nice little monthly announcement like "People of Islam, this month the citizens of Istanbul are counting on you to put an end to terrorism". Make all of Islam our unwilling allies in the fight against terror.
Sigh... one can fantasize, right?
