CTOTH, the first link doesn't say anything about 'uniformed' Iranian troops, just Iranians. That would be akin to saying we've engaged Saudis in Iraq. The second link is the raid on the Iranian Consulate in Kurd controlled Iraq, which could be construed as an act of War on Iran by the US.I think I heard it on Glenn Beck but I couldn't find anything in writing that states they have been confirmed to be engaging US troops but nonetheless a few links for you.
