Really no reason to be afraid of Retaliation.  The chances of Al Quaeda making another terrorist attack is no greator, no less than usual.  Osama being dead is kind of just a martyr for them.  they’re still going to try and attack us, like they’ve been continually trying since September 11. How else can they really change if you think about it.  They lost the leader, but it like most terrorist groups or pretty de-centralized (hence why it took so long to find him in the first place), they don’t really need or operate under a leader.  They’re already secretive, with many members just because they’re angry now doesn’t make them anymore or any less successful
