Don´t worry, the Iraq war destroyed all the US reputation, but Barrack Osama will build it up again! :-/
I wonder what you mean by this. Is this sarcasm? Or are you venting a little of your own angst towards America here?
The first half of the sentence is the present, the second is the future. My Icon is an expression of sadness/anxiousness. Although I think that Mr. Obama will make America looking better in the eyes of the world, because he won´t act "unilaterally", he´s also the worst choice for the global problems. So while I hope that the US reputation will increase (because you are our natural friend - given our cultural bonds), I hope it won´t be Obama doing that, but McCain.
