In The Nation: "Targeting Tehran," Michael Klare's review of the Bush ramp-up, rhetorical and physical, over Iran. Among the latter:

"The deployment of a second aircraft carrier to the Persian Gulf region, along with an accompanying array of cruisers, destroyers and submarines. Several additional US and British naval minesweepers are also being sent to the Gulf -- a clear indication that senior commanders anticipate Iranian efforts to block vital oil routes in response to any US airstrikes."

And "The decision to replace the outgoing head of the US Central Command -- which oversees US forces in Iraq, Afghanistan and the surrounding region -- with a Navy officer, Adm. William Fallon. It makes no sense to put Fallon, a former carrier group commander, in charge unless the next phase of combat in the region will emphasize air and naval operations against Iran."

Klare urges Congressional hearings and sets out the questions that should be asked.
