U.S. ADDS FORCES IN PERSIAN GULF to deter the Iranian military from any possible attempt to shut the Strait of Hormuz.

MORE: Iran declared Wednesday that it can destroy nearby U.S. military bases and strike Israel within minutes of an attack on the Islamic Republic.

I would suggest that the U.S. respond by simply mooring an old barge painted with a target on its top a few miles offshore from Iran and then firing a single unarmed ICBM at it from U.S. soil. At that point, a simple note stating that 'we know where you are' should suffice.
