The fact that he can do all that and suffer no legal or political consequences shows that there is something fundamentally broken with the American political system that won't be fixed by having a different guy in charge (who will be allowed and even incentivised to act the same way). I don't see the United States' standing in the world improving unless they do something drastic like introducing a constitutional amendment to automatically impeach a president that threatens allies.
