Interesting! So you advocate that Americans do away with (or just ignore) their 4th, 5th, 6th and 14th constitutional amendments that provide right to due process of law, so that a president can order the assassination of any American citizen as they choose? Maybe with the caveat that targeted citizen has to have (at least in the view of president) endorsed violence on the internet?
Is that your position?
That may well be a valid position to hold.
But then you cannot, in the next sentence, claim that America is a system of law and order, democracy, etc., or that it is any better than a dirty little dictator like Putin, who we are fond of claiming kills people without due process.
You can?t have your cake and eat it too.
