Really? He lies? Or just obfuscates? What else has he obfuscated?
C'mon, get real! Do you really expect a man who is dealing with our mortal enemies to say just what he's thinking? And how would such naivete help us? Folks with a smidgen of sense can distinguish between things he really believes, and those he has to say for diplomacy's sake. Perhaps you expect him to also announce our troop movements to the world.
