Warmer relations between the West and Russia.
What remains of the West. Today, 'the West' encircles European Russia, in TTL, the West would stop where it once did, at the hem of the Iron Curtain.
An alliance against what though?
And that would not be looked on warmly anyways......
The days of alliances against things are over! At the break of this new dawn of peace between East and West let there be a new alliance, an alliance for something. An alliance for freedom, democracy, and world peace! You know, something ninetiesy and optimistic. A Russo-American Alliance for World Peace would probably fly pretty well in both Washington and Moscow.
Although in this scenario, some European states might feel a bit squeezed. Basically, my opinion of post-'91 East-West relations is that the USA has been too antagonistic towards Russia, and the EU hasn't been antagonistic enough. The entire European project depends on a weak Russia, so its in our best interests to keep the Bear down, but the USA doesn't depend on a weakened Russia, indeed, antagonising them runs the risk for them of reigniting the Cold War. Obviously I'm grateful that I live in a TL where the USA did support the EU's
Drive to the East, but if I were in charge of American strategy since 1991 I wouldn't have done the same, I'd've disbanded NATO and replaced it with a new Russo-American Alliance for World Peace; I'd echo Moscow's scepticism about EU expansion and support the integration of the CIS.
