Yep, that first part really strucked me as well when I was able to watch US 'news' broadcasts in Canada. There even was one frightening "report" about the anti-american EU superstate .. which.. erm.. doesn't even exist
now. o_Ô
And I'm not sure the argument "because America's the boss" fits too well here. Anti-America bias has grown after 9/11, and that's exactly because America is ceding to be the world's sole superpower.
So it's more like the boss is showing his cracks and faults near to retirement, and now everybodies picking on him.
