That's not bashing to you and me, but "bashing" is a moronic and subjective term (that is, like "propaganda," it's only "bashing" when those who oppose you do it...) and a lot of Americans would consider it to be so.
But, yeah, this is presented as "america-bashing" in the US press because no reasonable person could possibly oppose US policy.
It's the nature of national identity to define yourself against another - and even Europeans do it.
However, Spain managed to win the Euro2008 without being able to agree to a lyrics for its anthem. Now that's a feat of 'soft' national identity.
While you might perceive some Europe-bashing from Obama, I think you'll also perceive some flattery as well.
I don't even think he knows the answer to that... "Pretending that you already know the answer when you don't is not actually very helpful." ~Migeru.
