Recently there was an article on the web which stated that a 'low-level' cleric (I don't know what that means) gave bin Laden the OK to kill 10,000,000 with a nuclear device--essentially, the cleric said that that would be OK with Allah. The target was, of course, the USA. I cannot see any country that possesses nuclear weapons letting that ride. I think the response would be devastating. It would have to hit more than one or two countries. Other countries/states that have nuclear weapons and delivery systems--even if that means trucks or luggage and people who are willing to take their chances--would likely see that as an opportunity to even some scores and harm some enemies. In the carnage, folks could sit back and say, "Who? ME? No way." IMO, we are closer to WW III than ever in our past. I include the Cuban Missile Crisis in that remark. We just ain't learned jack shit in forty-four years.
