A sampling of his character:

1. Walks with Trump across the street for the bizarre Bible photo op, when an honorable man would've declined. Then, afterwards, writes about what a fiasco it was. Blames others.
2. Tells Chi-coms he will give them forewarning if the democratically-elected president makes a move against China. What would be the only accurate term for that?
3. Throws a majority of grunts under the bus by supporting the idea that they should be subjected to the moronic ramblings of neurotic defectives who evangelize a weird cultism that divides people in every institution it touches, all as an effort to pander to a political base of the current commander-in-chief to whom he's willing to whore himself.
4. After the Afghanistan disaster, he immediately claimed that he warned against the "no-plan pullout," but wasn't listened to. Blames others.
5. And then, according to Johnny Quest here, he lied yesterday about American military hardware not being left behind.

I have no idea how Milley was 40/50 years ago. Maybe he was everything you claim. I don't care. I'm talking about what he is. Now. In 2024.
