The U.S. is very lonely. There are a few dark blue countries but you can barely see them because they are so small (Israel and a few Pacific islands). Moreover, as I showed in an earlier post, the situation has gradually gotten worse. This cannot just be blamed on President George W. Bush: Alienation from the U.S. started before him and the tide was not turned by President Obama. Perhaps it is because of China, or domestic politics, or just the price of being the only true superpower.
For comparison, the map below is from 1995: There is more blue, although much of that is due to a few (rather important) countries: Russia, Argentina and Turkey. There is also evidence for the often-heard assertion that the U.S. pivot toward Asia has alienated Latin American countries. Asia looks a little less red in 2012 than in 1995. The reverse is true for Latin America.
Finally, a map from the Cold War (sorry, I was too lazy to adjust state boundaries). There are two power blocs that are heavily polarized with a distinct middle group of nonaligned states. We should be grateful that global polarization does not look this way in 2012.
