We know, because Joe Biden told us, that the Obama administration expects us to get attacked again domestically.
That's the working M.O. of this administration: no matter what we do, we're going to eventually get hit again. The Obama administration views the seven years after 9/11 as more a fluke than a successful strategy by George Bush to prevent domestic terror attacks.
So if the working theory is that we're going to get hit again, what is the best response? After all, the public does credit George Bush with keeping us safe at 9/11.
The best strategy would look something like taking a band-aid off quickly. Get the pain over fast. And if an attack happens quickly enough into the new administration, they can blame Bush.
So the Obama administration is working hard to release all the memos on interrogations, change all the policies Bush implemented, and clear out the old as fast as possible. Never mind that if it were done slowly over time, our terrorist enemies might not be so incited to attack.
If your working premise is that they are going to attack anyway, get them incited quickly, get it over with, and blame Bush.
There is no other justification for so quickly making us less safe.
