I agree with the first bit (I watch Discovery). However, I seriously doubt Biden is a target (unless Obama decides to bump him off). Is it possible there are other important things there? There probably are and I can see it being on a list of targets, just low on the list. Question, was this pixellated before. I probably got the address wrong, but I think this is an image of a nuclear power plant in the state I work in.
I combined my answer to your last point with my answer to GG.
I actually think it is a mistake to unblock satellite imagery of military installations. I would guess that cost money to do, seeing as how Bush's policy was already in place. Possibly not much, a few thousand dollars perhaps, although my guess is tack on a few zeroes. I cannot see any benefit for the images to be available, except possibly demonstrating that the US is more open and free now. Somehow, I doubt that made a blip on the popularity scale on a global level.
As to the military viewing Obama's policies as potentially hostile, I would not be shocked to see fairly huge cuts to the military (Navy and Air Force first) in the next few years. Something has to give budget wise and that is my guess what will have to go. There have been some cuts, but I expect more dramatic ones.
