I have always had mixed concerns about Gen. Mattis. I do not like how he turned his back on his Marines in Haditha,Iraq.
I'm not sure what you're referring to, Top? The Haditha incident occurred in November 2005 - Mattis was already serving at MCCDC, so he couldn't have had anything to do with the incident on the ground.
Aside from that, Mattis was later the convening authority for the courts martial, "And as the convening authority who signed off on many of the key decisions along the way, including granting immunity to Marines who, the forensic evidence suggests, may have committed serious crimes, Mattis made such an outcome all but inevitable, the film contends." https://www.businessinsider.com/haditha-film-raises-questions-about-mattis-role-in-iraq-war-massacre-2018-4
Sooooo, judging by that Mattis granted immunity to most of the folks involved, and the prosecution's case fell apart.....except against one Marine who pled guilty.
Not really seeing how he turned his back on anyone - he didn't force the Marine to plead guilty and he signed off on immunity for just about everyone else.
I'd be more pissed at murtha (spit), who, from the floor of Congress, declared the Marines guilty before a trial was ever held.
I will say, that I have met Mr. Mattis. I found him to be genuinely concerned for the welfare of his Marines, and genuinely concerned for not just a competitve edge on the battlefield, but to "overwhelmingly tip the scales in our favor." He seems one who searches for the best solutions no matter who has them. And aside from that, demanded action and deed over words.
Those are just my observations......you may have insight I don't.
