Why heavens, he's a Nobel Peace Prize winner so he must have an impressive resume for others to respect & honor.
However, he is proving more & more to be merely an empty suit who can read soaring rhetoric very well. He's not helping America at all in his overseas travels--it is evident from the response on his latest trips that the bloom is off his rose. His self-inflicted wounds from a misguided domestic policy that entailed violating every aspect of Economics 101 has left him greatly weakened at home & abroad.
I've yet to see any indication that he has the political cajones to track back to the center & govern in a manner that'd give him credibility on the homefront, which can be parlayed into having more weight in foreign affairs.
But what do I know?
