Reason said that the fall of the USSR had more to do with the voluntary acceptance of youth of rebellious popular culture that was voluntarily disseminated by artists, and less to do with the bankrupting of the country through proxiwars fueled by involuntary american taxes.
if that is true, then not only was the subsidizing a waste of our money, and immoral because it involved violent theft of that money in order for it to be spent, but it was a disaster, because it helped to fuel the radical islamic militancy that now haunts us today.
and even if that subsidization DID help us to destroy the ussr, the ussr wasnt an almighty omnipotent enemy to begin with. they did not pose as much of a threat as everyone liked to believe, and precisely because it was so statist in its economy, odds are it was gonna fall of its own bureaucratic weight anyways.
