He stabbed Trump in the back for wanting forces removed from Syria. Mattis is in the “remove Assad and install a sunni government” camp. He is also a never married bachelor who refused to execute Trump’s orders kicking out trannies too.
That’s a little strong. Mattis didn’t stab Trump in the back. He provided his warriors opinion, and when Trump said he wanted to execute differently, he offered his resignation. Both men are right, they just disagree.
As far as the political issues, Mattis, being a true warrior, probably just didn’t want to deal with the politics, and there were plenty of legal issues to be dealt with before anyone could kick out trannies in any case.
I think you and I would be on the same page regarding the trannies in the military issue, but as Donald Rumsfeld once said, you go to war with the army you have. And Mattis was focused on the war. Not the politics.
I find it astonishing that a man of his age and public notoriety has escaped any mention of romantic involvements. What is he - a monk?
