Hmm, I'd also like to see some suggestions to forcibly remove the Capitalists from Africa, rather than to just beat them to the punch at colonising. I'd also like to see some more arguments for intervention in Asia, since what Engels said isn't true; the Asians had been dominated by elitist rule for much longer a time than Europeans.
Another question of plausibility: Why were the Marxists such strong supporters of pensions? Wasn't it the Utopian idea that the elderly should commit suicide as a service to the state? If I remember correctly, some of Marx's students committed suicide because of this.
Also... How about a disenfranchised Bismark showing their face? Maybe Otto's son Herbert. Clawed his way from the bottom of the army after his father was stripped of his pride and land? Seeking revenge?
