An idea of, 'Confederation of Independent States' appears to have sprung the USSR into a US pre- Civil War scenario.. all unprepared and with the focus upon the chimera of 'Capitalism' while destroying the synergy of a (truly) federal grouping by choice.
Then too, the official US laissez-faire policy, augmented with the worst of capitalist exploitation of the new kids - guaranteed to create mistrust of a whole new kind between US/ former USSR States: simple greed, dissembling in action. We stood around impotent and disinterested - rationalizing away great opportunity for real assistance and long-term mutual benefit. And the Jingoists' greatest fear was realized: nothing left to Hate! unquivocally.
(My thought at the time of Berlin wall was: had we granted the remnants a blanket half a trillion $, spread over a time that reflected their ability to use it sanely: we would have been ahead of the M.A.D. incipient oblivion game, echoed the ideals of the Marshall Plan and - probably made more $$ over the period of disbursement than we gave.) We have few with any vision, especially among the sated.. Gawd are our present Dynasts unutterably boring in their aim for ez short-term killings.
In brief - hindsight being so handy - it's easy to plot a quite different course than what has occurred: a US-aped concentration of the newly divided pie into the same sorts of pockets as in the US. As in US, where the same 3% of the GDP is shared by ~ 13,000 at the top - and 20,000,000 at the bottom, the mass of the Russ poorest got screwed with outside help from real Pros - US.
So are 'we / all' better off, despite the tawdry rapine? Yes re the reduced likelihood of MAD ICBM scenarios - but we all have done poorly compared with your hypothetical of a saner transition. Would need to know more details than I do, to estimate whether Gorbachev lacked crucial other qualities to accompany his obv intelligence, or if: the factions were simply too stubborn to ever cooperate effectively (?)
A nice what-if, but moot.. Putin has a scary side, but also is too complex a guy (like K?) to be pigeonholed with old rubrics.
