Because McMaster objected to the label “radical Islamic terrorists” in a meeting certainly does not mean he is unfit to serve. Did you read the article I posted on his service record? I think that counts for a lot more than rejecting a label. He is a pioneer for having deeveloped the successful strategy now used in the Middle East. I would add that there are so many false reports flying around attributed to “sources” that I mistrust them all as gaslighting.
edit: Also, looks like the original source of the story you posted is the New York Times. Need I say more?
