This is a false comparison. We were at war with Germany and were trying to obtain the element of surprise in the fight against EVIL. In this case, the American people are being lied to about the true nature of our enemy (Islam) and we are allying or trying to ally ourselves with our enemies (Syria, Iran, Saudi Arabia, Egypt, Pakistan, etc.).
And we are presently at war and are trying to obtain an advantage by systematically attacking terrorists. In order to do so, we must (at a minimum) keep the rest of the Muslim world placated, so that we can direct the full brunt of our effort toward the battle. IMHO, lying in order to do so is the proper course of action.
