Regime change in Iran is imperative. Nutjob has gone out of his way to draw the battle lines. He used threats to wipe Israel off the map, hosting the racism conference which questioned the Holocaust, and thumbing his nose at the world regarding nukes and threatening proliferation, to start the angst. Iraq, IMHO, was part of the larger picture-occupation of Iraq and Afghanistan sandwiches Iran between them. The beauty of it is, is that NATO troops(read Europe), will be right in the thick of it, if Iran makes a move. Troops already in place in a theatre, make it difficult for political wishy-washiness..
