It's natural for "blocs" to form against dominant powers...as the US.
But this Sino-Russian bloc could be especially troublesome with Russian resources and Chinese "dollars" betting against the US...
Then of course there are the Oil Barons of Araby and the Empire of Islam, a/k/a "The Evil Ones," on whom Dubya as "declared war"...in the nicest possible way. To wit: Support the Israeli "land grab" on the West Bank, or we'll bomb you, and call you a terrorist, or a state supporter of terrorism...
And then come the Euro-social Democrats who always hate American first...
Finally, we have Dubya & Co who are so easy to hate...inside or outside the US.
The very notion of An American Superpower...seems obsolete in the current geopolitical situation. Why is this important? Well it isn't. Yet....but it will be. Soon. The big geopolitical chickens always come home to roost...eventually.
