I think your point is well taken about islamo-imperialism serving as a catalyst for the reshaping of national interests and global alliances. The by-product of this is, as you so correctly pointed out, is causing a fundamental rethinking on the part of Russians, American, and others (Indians, Chinese, Turks, Israelis) about how to deal with this metastisizing, cancerous, islamic fundamentalism. I think Vladimir the first realizes that the modern day Tatars are knocking at the door. Russia has a very overexposed underbelly, and needs allies. I suppose it doesn't hurt to have the last remaining superpower as a friend. Hence, I think the relationship can only get better.
