While I don't really agree with political assassinations, and you are likely to get flagged for this, it's not like the US government hasn't done similar stuff to leaders that we thought were harmful.
The CIA tried to kill Castro a bunch of times [1], presumably because they felt that him being in power was harmful and killing him was a net good. It's not like this kind of stuff is unprecedented.

It am not calling for a "political" assassination. The problem with him is not that we disagree on policy matters. It is that he is an idiot and that he will kill millions of people at random out of sheer stupidity. I am calling to kill him because as an idiot, he can't be "convinced" to do otherwise. There is no debate nor discussion nor negociation possible.
