Trump has made mistakes, as like the Left point out, his choice of fashion, dance style and anything else that doesn't fit the Media of Music & Entertainment narrative whose political enterprise is based on archaic Westernism (Rome & Athens).
But Trump is in Politics to be Political and not a Media suck up.
So politically, no big mistakes at least in a country that made the biggest mistake of rejecting British politics of modernising Westernism that changes to the tune of the whole world via its Commonwealth. America's mistake was to embrace the mainland European powers which was a bad move. Thus Germany & Confederacy failed.
Thus why France & Democrats are failing and why too Italy/Greece & USA Media will fail.
So I very much know you won't have a valid argument in your next post to explain a counter against what I've just said. Even if i told you the process of why and how Islam & Israel will one day be united. I doubt you little Media mind could ever cope with that inevitable act in time.
...because YOU DO NOT KNOW what's really going on and why things happen the way they do.
Trump will fail to make America a modernising Westernism against the established Archaic Westernism . But he's done the job of showing the evil in what makes America no different to Communism, Terrorism & Dictatorships that justify the Left's archaic Media Westernism version. He's shown the world the chink in the American Dragon's armour.
And there is no going back.

...ahhh. The irony of Aistralia being a Criminsl nation.

Looks like it was the USA all along.
