That's brilliant. I've not heard him called that before.
As has been mentioned, there are plenty of checks and balances in the US to rein in the worst excesses of Agent Orange. Just look at how the courts have refused to be steamrollered over his anti-muslim travel ban. In such a legalistic country, it's highly unlikely that the President can get away with behaving in an unconstitutional manner for very long.
From a defence/security point of view, as I've said previously I have the highest regard for the National Security Advisor, General HR McMaster.
