Yeah. I actually get a little concerned on significant dates like this one. The Jihadists are fond of doing things on dates that have some meaning, to them or to us. That's one of the reasons so many people have looked so hard for the significance of the August 22nd date that Iran said they were going to provide their response to Western demands about their nuclear program. The best info I've found on that is that, this year, that date lines up with the Muslim calendar so that it marks when Saladin conquered Jerusalem and took it from the Christian Crusaders.
If Al Qaeda has a nuke they'd use a date like that, or today, to unleash it on us. Imagine the rationalization by the left if someone set off a nuke in Washington today and then said it was in revenge for us having nuked Hirshima.
Well naturally they'd all understand it and blame America for bringing it upon itself. Except for the leftists in DC, who wouldn't be available for comments!
