Larison puts US meddling in Georgia into perspective:
The claim that the U.S. rejects spheres of influence is true only in the sense that our government rejects it when other states claim them. For our part, the entire world is treated more or less as our sphere of influence. As long as Washington treats the rest of the world this way, other major powers are going to try to gain influence anywhere they can. Indeed, other major powers would be doing this anyway, but there is no way that the U.S. and other major powers could ever come to any understanding about respective spheres of influence so long as our government insists that we have them all and they have none.
