In a military confrontation Iran could inflict serious damage

ISTANBUL — Tehran has stepped up its bellicose warnings of conflict in the Persian Gulf as potentially crippling new European Union and American sanctions have been approved on Iran's oil exports and central bank.

The US defied the warning of a top Iranian general this week and sent the USS Abraham Lincoln – flanked by British and French warships – through the Strait of Hormuz at the mouth of the Gulf. A senior Iranian lawmaker scoffed that the US "did not dare" to send its ship alone, because of the danger posed by the Islamic Republic. If Iran were to close the strategic waterway, as it has threatened to do, the American aircraft carriers "will become the war booty of Iran," he declared.

Such bluster is not all talk. The US may outspend the Islamic Republic nearly 90-to-1 on defense. But Iran, heir to ancient Persia's naval innovation, has a well-honed asymmetric strategy designed to reverse that advantage.

A 2002 US military exercise simulating such a conflict proved devastating to American warships.
