i was in London the other day and there was an interesting program on TV with some ex-SAS officers talking about assassinating Saddam Hussein.
Basically, everyone agrees that he is pretty difficult to find even if someone wanted to. he never sleeps in the same place twice, no one ever knows where he is going or where he will be except 1-2 close security agents at the last minute. His own kids cant talk to him without a written request in advance. he has countless doubles. a pudgy Middle Eastern guy with a thick black mustache is not exactly rare that part of the world either... he apparently is known to travel around the country by himself, driving in civilian cars or delivery vans, in civilian clothes, rather than conspicuous convoys of security agents and body guards.
Mossad has planned on several occasions to take him out. they are a world favorite in the "kill Saddam game" by far. apparently they are VERY active in making people dissapear worldwide and in the Arab world. They tried on a couple different times to kill Saddam and failed.
the US fired a missile into the front entrance of the Al Rashid hotel in Baghdad during the Gulf War, knowing that he was in a bunker under the lobby. but of course, the journalists that were living in the hotel did not appreciate it or find any sense of irony or humor in it at all.
