Perhaps these statements are true, but he also fought a series of losing battles as part of a series of losing, genocidal wars.
The Persian Gulf War, the War in Afghanistan, and the Iraq War — only the first one could be considered anything other than a complete failure, and even that one wasn’t a success since they had to wage another war with the very same government a few years later.
One of the many things that led me to leave America was its veneration of its bumbling military, a Keystone Kops army that has waged warfare continuously for over 70 years, and lost almost every engagement in the last 50 while spending the inconceivably vast sum of $20 trillion dollars — that’s twenty million million dollars — while America publicly mocks the military history of places like France, a country that has literally a thousand-year history of military excellence (and I would add that if you asked a non-American to name a great general, it would almost certainly be Napoleon).
Oh, and endless war crimes. Yes, the endless war crimes were a really big deal to me.
So as far as I’m concerned, Mattis can get stuffed — that’s shorthand for, “He should be on trial at The Hague like all senior American military officers and political leaders in the last fifty years should have been, and should die in jail.”
