Lets say the president of IRAN, Mahmoud El Paedophile Ahmadinejad, just arrived to the hotel where you are working at, and your mission is to prepare him the dinner. In the meanwhile, 2 men in black appear and tell you "Chef, put this powder in the president's meal, dont ask questions, just do it, and if anything goes wrong, the goverment will not recognize anything of this, do it for america" (like it usually happened with John Rambo).
Would you do it?
