Obama didn't "give" any rights to the underwear bomber, at all. Those rights were already in place, enshrined in the Constitution and 200 years of legal precedent. Same as with Timothy McVeigh and those who executed the first WTC bombing.
As for the situation wrt Pakistan, Afghanistan, and the WoT, the Obama Admin has inherited a completely botched job, a cock-up of epic proportions. I'm not really in favor of using drones to attack targets except in situations having rock solid intelligence and where collateral can be held to an absolute minimum. Which would be quite rarely. Substituting technology for valor at the squad level probably creates more enemies than it eliminates. If we weren't willing to take casualties, to have some of our troops make the ultimate sacrifice, we shouldn't have been there in the first place.
I am appalled that the Obama Admin has not brought those currently held as detainees to trial of an honest sort. Their calculations are purely political in that regard, being apparently unwilling to take the political flak from revealing Bush Admin policies for the sham and the travesty that they are. If the govt can make a case against a detainee, good, do it. If not, let 'em go. Justice, as defined by the Constitution and the people who wrote it, ratified it, demands nothing less, regardless of the perceived risk involved.
