A plan for war against Iran?

CNN has a story titled What war with Iran would look like. Here's an excerpt.

A deployment of minesweepers to the east coast of Iran would seem to suggest that a much discussed, but until now largely theoretical, prospect has become real: that the U.S. may be preparing for war with Iran.

It looks like the plan is to use mostly air power.

No one is talking about a ground invasion of Iran. Too many U.S. troops are tied down elsewhere to make it possible, and besides, it isn't necessary. If the U.S. goal is simply to stunt Iran's nuclear program, it can be done better and more safely by air.

Personally, I think attacking Iran is long overdue. We simply can't afford to have "the world's central banker of terrorism" (Condi Rice's words) to have nuclear weapons.
