With your focus on death as punishment — the day after an apparent assassination attempt no less — it seems we have less in common than I supposed. I’m not with you after all.
And if we find out that at least one of these assassination attempts was staged as a part of the greater kayfabe, what would your reaction be then?
Aside from the point, my support for judicial executions due to treason against the United States is not support for extrajudicial executions, like the ones that ICE has been carrying out. I think Italy and Romania are decent examples of countries becoming better off after executing their authoritarian figureheads, although I don’t think that there are grounds for that in the United States yet.
Execution != assassination, as the latter has a lot less success in creating real, long-lasting change than the former.
Neither the Butler, Pennsylvania nor the White House Correspondents Dinner incidents were staged — that's conspiracy theory nutter nonsense.
(Not that there aren't elements within the Trump administration who might contemplate a false flag operation, but it will be obvious if they try it because they aren't clever enough to pull it off.)
Furthermore, both Ceaucescu and Mussolini were extrajudicial executions.
Nixon is a better precedent for the USA because it demonstrates that we're already capable of ejecting a criminal president without bloodshed. It wasn't a perfect process (the Ford pardon was terrible) but in the end Nixon still lost power.
