The terrorists responsible for Mumbai are not from Iran or Syria. Early reports sound like they are Indian. And if that is true, your idea of 'No diplomatic relations with those that disagre with us," is flawed.
Diplomatic relations??? Muhahahahahahahahahahahahahahaha. Are you daft? The terrorists don't have any diplomats. They start cells in every country with other like minded fools who believe if they martyr themselves Allah will see to it that they go to heaven for killing innocent people, where they will have 72 virgins waiting for them. What they will do with them is something that is as laughable, as your diplomatic relations for terrorists.
You my friend are a good candidate for the "Darwin" award for stupidity.
