However, i believe one important piece of information is missing from most articles i read about this topic; Obviously it is much harder to create/restore something than it is to break something. In my opinion Bush made a big mess and Obama is doing a great job turning the whole thing around and leading the Americans in the right direction. There is only so much one person can do, and besides that, change should always happen slowly to prevent instability.
We forget that the reason all of this was possible in the first place are obviously the American people itself; For example why on earth did they vote for George Bush the second time... From my point of view, the Americans have some kind of unrational fear of terrorists and choose to give up all privacy because they believed it would give them more security. Instead, it gave them another terrorist: the NSA.
Hopefully they will learn from their mistakes and continue in the right direction. I believe Obama started of good and hope he will continue to do so.
