Well it figures an American would say something to me about that. Go figure.
It's the worlds worst kept secret, quite a bit of the world don't like America(mostly so in developed nations). Obama has definitely given America a huge boost though that's for sure.
Yet these Americans are going against him; even when what he did in Japan helped
American-Japanese relations. This is where my comment fits in. Very nice.
EDIT: From 2002-2007 the world image of America declined quite a bit. Most countries had 50/50 favorable-unfavorable outcome towards America. Countries that liked America most were mostly from Africa. (Ivory coast was #1 88% favorable... Compared to America itself with only 80% favorable.) View of Americans themselves has declined as well but not as much as the view of the country as a whole. In fact most countriese hold a 'slightly favorable' position on Americans.
So when American worldview is declining it's fair IMO for me to state that I think that the behaviour and views of Americans is one of the reasons for this.
