Interesting read on Iran.

[24champ]

The U.S. government has taken some preliminary steps that go beyond planning. The Washington Post has reported that the military has been secretly flying surveillance drones over Iran since 2004 using radar, video, still photography and air filters to detect traces of nuclear activity not accessible to satellites. Hersh reported that U.S. combat troops have been ordered to enter Iran covertly to collect targeting data, but sources have not confirmed that to The Post.
