I wouldn’t minimize the comparability when there are such blatant examples of Trump utilizing Nazi propaganda like the Big Lie and the demonization of an out-group, like the Nazi’s antisemitic populism, to gain power.
Prior the Reichstag fire, the Nazi’s electoral high point was 37% in 1932 (or 31% of Germans at 82% turnout), compared with Trump at 49.8% last year (or 31.8% of Americans at 64% turnout). The point being that you don’t need a significant buy-in from the people to elevate leaders with dictatorial motives. You simply need a triggering event which they can use to justify their consolidation of power permanently.
Also, if the desire is to avoid authoritarian leadership, I’m not sure military coup is the play. I know the American Armed Forces swear an oath to uphold the Constitution, but it seems that would get real tricky once you’ve overthrown the Commander in Chief, in defiance of the Constitutionally mandated chain of command.
Bad Canada. Stop helping those who threaten you.
