Trump wrongly charged Chad with being terrorist supporters and put Chad on his Muslim Ban list.
The truth was, Chad was helping us fight terrorism and Trump ended that with his mistake.
Trump's mistake seriously undermines stability in the whole region.

(…as an aside, this wasn't the first or only mistake Trump has made that has cost us to lose strategic advantages in the world. The truth is, Trump is a threat to our own national security and he has directly caused our own forces to be in more danger because of his willful stupidity, …that or he's actively working for our enemies at the behest of his puppet master Putin. I'm going with the latter.)

Impeachment is too good for Trump, he should be tried for treason too.
