I'm expecting that someday the Russians will be withdrawing to the Ural mountains, but from the Easterly direction.  That will be during the war with China, and that's scheduled for some decades out.

The philosophical justification that the 'unipolar world' people have for their aspirations is that it will 'end war' when we are all holding hands and singing cum-ba-ya (and eating bugs, owning nothing, and being happy.)  Of course this is a pipe-dream and it's kind of the 'upper-middle class' useful idiot types who even need to grasp on to some ethical teddy-bear to justify their efforts.  These types fill in the middle of the pyramid.  Those nearer to the top who make everything happen are not nearly so sentimental and burdened with the need for garden-variety psychological crutches; they've got their philosophical and ethical issues worked out long ago, and it's and easier row to hoe for people who are true psychopaths.
