If the US goes into Iran, it's going alone.

After being tied down in Iraq, and the horrible catastrophe of Katrina, there is increasingly little support and less logistical capability, to militarily go after Iran. That is probably why the Pentagon planning document suggesting that the use of Nuke weapons on WMD sites was leaked, to give Iran the belief that we might be able to do something militarily to stop them. But it's looking very likely that the US will not even be able to bring Iran before the security council.

UNITED NATIONS, Sept. 15 -- Despite an intense lobbying effort at the most senior levels, the Bush administration failed to persuade three key countries Thursday to back the United States in pressuring Iran to give up sensitive aspects of its nuclear energy program, diplomats and officials said.

Russia, China and India either publicly or privately turned down U.S. requests to help report Iran's case next week to the U.N. Security Council, which has the authority to impose economic sanctions or an oil embargo.
