Later in Hitchens' life he conceded that he believed Trotsky (near his own end) realized that the whole experiment was based upon a false premise: that the working man could elevate himself into leadership and develop a fair and just system. My reading of Trotsky's last works doesn't completely bear that out explicitly, but reading between the lines one can certainly come to that view.
Clearly then: Trotsky was dead-on, not just re his cohorts but
in Spades re the dis-US also-too (beginning earlier ~'68 assassination-fest). Alas for all that immersed brilliance re vacuuming-out the Religio-noisemakers: that plot failed in USSR and ..for Murica/'18? ..scatter-bombing with Orange-boy's on-order friendly-nukes? (wouldn't work either).
