America lost its credibility no matter how you put it and that's the reality of last 8 years. With insane foreign politics and all outcome with it.  It became clear that US is not what it has been promoting. Unfortunetly, it's a sad  part of all this. There has been a sense once that American principles were truly an awesome thing but situation quickly reversed over the years which proves that history repeats itself over and over again. 8 years of Bush just confirmed that even "democracy" like America is not perfect on top of american geopolitical agendas like oil and influence. America just gave away a biggest lie that it will bring democracy and freedom to the "oppressed" world and  this is hurting truly the idea of free society. It's just pure geopilitical agenda and that's what it is.
