Is the U.S. stepping up preparations for a possible attack on Iran's nuclear facilities?

The Pentagon is always making plans, but based on a little-noticed funding request recently sent to Congress, the answer to that question appears to be yes.

First, some background: Back in October 2007, ABC News reported that the Pentagon had asked Congress for $88 million in the emergency Iraq/Afghanistan war funding request to develop a gargantuan bunker-busting bomb called the Massive Ordnance Penetrator (MOP). It's a 30,000-pound bomb designed to hit targets buried 200 feet below ground. Back then, the Pentagon cited an "urgent operational need" for the new weapon.
