No Doubt They're Quaking

This would seem almost like a joke if it weren't so deadly serious.

An increasingly defiant Iran, resisting pressure to halt its uranium enrichment activities by a Thursday deadline, inaugurated a heavy-water nuclear reactor Saturday and then, as if to punctuate its point, fired a long-range missile on Sunday from a submarine in the Gulf.

The U.S.'s response?

Washington, in its own diplomatic escalation, has increasingly dropped hints that the United States might organize tougher economic sanctions against Iran, independent of the United Nations, if the Security Council fails to do so.

Yes, that should have them quaking in their boots.
