US and the assassination of an Iranian scientist

Political talk shows are really hilarious on Hurra TV. I put it on in the morning as I get ready and have breakfast and read the paper. I watched on today moderated by former Lebanese Marxist, turned right-wing sectarian Christian, Sam Munassa. The round table was discussing the possible responsibility of the US or Israel in the assassination of the Iranian nuclear scientist. They all agreed that the US and Israel would never ever engage in assassination, and that it is inconceivable that the US would do such a thing. Two Arab fellows from DC said that the US can't possibly do that because they would not risk "their men" in the field. I almost spat my tea from amusement. I also noticed that Hurra pundits pay regular tributes to Jordan, Saudi Arabia, and Egypt.
