This looks ominous:

Three weeks after Tehran threatened action against any US aircraft carrier entering the Strait of Hormuz, Washington made two moves: US Defense Secretary Leon Panetta disclosed Sunday, Jan. 22, that the USS Enterprise Carrier Strike Group would steam through the strategic strait in March; a few hours later, the US Navy sent the USS Abraham Lincoln carrier through the strategic strait without incident, accompanied by British and French warships.

The Enterprise is scheduled to be decommissioned after this deployment. I saw a figure a while back regarding how much it would cost to scrap the ship, and it was staggering. Be cheaper to just sink it somewhere over there and claim the Iranians did it. Don't forget that Dick Cheney talked about disguising U.S. boats to launch "surprise attacks" on larger U.S. ships.

The Debka website also reports that Nobel Peace Prize winner Obama is massing troops in the Strait of Hormuz:

The article "Massive US Military Buildup on Two Strategic Islands: Socotra and Masirah" is an exclusive article and can be purchased.

I'm not a paying member, but I saw mention elsewhere that Obama's putting 50,000 troops on each island. They'll be in place by March, just in time for the Enterprise to make its trip through the strait.
