Umm nothing is going to happen on the 4th of July. Bin Ladin might release a tape just to piss the americans off but the chances of a terriorist attack are virtually non exsistant IMHO. The bad guys don't usually annouce the day they are going to attack. If they had a nuclear device they would have used it instead of hijacking plans.
Attacks against American interests around the world are much more likely than attacks in the USA. If the bad guys are smart they will just go to ground for a few years and then hit America again when they arnt expecting it.
