More hype about Iran?

Back when I started writing this blog, I warned that the idea of preventive war against Iran wasn't going to go away just because Barack Obama was president. The topic got another little burst of oxygen over the past few days, in response to what seems to have been an over-hyped memorandum from Secretary of Defense Robert Gates and some remarks by the chairman of the joint chiefs of staff, Adm. Michael Mullen, following a speech at Columbia University. In particular, Mullen noted that military action against Iran could "go a long way" toward delaying Iran's acquisition of a weapons capability, though he also noted this could only be a "last resort" and made it clear it was not an option he favored.

One of the more remarkable features about the endless drumbeat of alarm about Iran is that it pays virtually no attention to Iran's actual capabilities, and rests on all sorts of worst case assumptions about Iranian behavior. Consider the following facts, most of them courtesy of the 2010 edition of The Military Balance, published annually by the prestigious International Institute for Strategic Studies in London:

GDP: United States -- 13.8 trillion
Iran --$ 359 billion (U.S. GDP is roughly 38 times greater than Iran's)

Defense spending (2008):
U.S. -- $692 billion
Iran -- $9.6 billion (U.S. defense budget is over 70 times larger than Iran)

Military personnel:
U.S.--1,580,255 active; 864,547 reserves (very well trained)
Iran-- 525,000 active; 350,000 reserves (poorly trained)

Combat aircraft:
U.S. -- 4,090 (includes USAF, USN, USMC and reserves)
Iran -- 312 (serviceability questionable)

Main battle tanks:
U.S. -- 6,251 (Army + Marine Corps)
Iran -- 1,613 (serviceability questionable)

Navy:
U.S. -- 11 aircraft carriers, 99 principal surface combatants, 71 submarines, 160 patrol boats, plus large auxiliary fleet
Iran -- 6 principal surface combatants, 10 submarines, 146 patrol boats

Nuclear weapons:
