First of all I would like to point out that the United States and Russia may have sometimes opposite national interests in Central Asia or Europe, but these two great powers also have one common enemy and that is Islam terrorism. Russia is fighting terrorism in Chechnya and even Dagestan, while supplying troops for Tajikistan in order to quell their own Islamic terrorism. The United States has just finished the operation in Afghanistan on destroying the groups that trained Chechen terrorists, while it is now preparing an invasion of Iraq where we actually have a terrorist in power. At the same time Israel is fighting its Palestinian terrorists(they have been reported to have made connections with Chechen "rebels"), and India and China are also solving their problems with Islamic radicalism. Let us all remember: We all stand together against Islamic Terrorism!
The difference between the West and the two mighty allies in the East - Russia and China - is enormous. In fact, it is not a difference, but an outright contrast
