Via Tom Tomorrow, we get confirmation that BushCo & the Pentagon are warming up the ol’ strategery machine again, pointing it this time at Iran.

According to current and former officials, Pentagon and CIA planners have been exploring possible targets, such as the uranium enrichment plant at Natanz and the uranium conversion facility at Isfahan. Although a land invasion is not contemplated, military officers are weighing alternatives ranging from a limited airstrike aimed at key nuclear sites, to a more extensive bombing campaign designed to destroy an array of military and political targets.

Preparations for confrontation with Iran underscore how the issue has vaulted to the front of President Bush’s agenda even as he struggles with a relentless war in next-door Iraq. Bush views Tehran as a serious menace that must be dealt with before his presidency ends, aides said, and the White House, in its new National Security Strategy, last month labeled Iran the most serious challenge to the United States posed by any country.

The challenge, of course, revolves around Iran’s potential to produce and use nuclear weapons. The same kind of nuclear weapons that Israel and the United States are “contemplating” using to get to key targets.

Pentagon planners are studying how to penetrate eight-foot-deep targets and are contemplating tactical nuclear devices. The Natanz facility consists of more than two dozen buildings, including two huge underground halls built with six-foot walls and supposedly protected by two concrete roofs with sand and rocks in between, according to Edward N. Luttwak, a specialist at the Center for Strategic and International Studies.

“The targeteers honestly keep coming back and saying it will require nuclear penetrator munitions to take out those tunnels,” said Kenneth M. Pollack, a former CIA analyst. “Could we do it with conventional munitions? Possibly. But it’s going to be very difficult to do.”

What’s that saying about teaching people that killing people is wrong?
