General Mattis supports the looters, cop killers, anti-whites, iconoclasts, and Antifa goons because Trump said mean words and wanted to get out of Syria. The so-called "color revolution" is gaining support.
No, sir, we could NOT unite without Trump, they won't let us. They only want destruction.
I see St. Mattis is still hella salty about his departure and not getting an indefinate embroilment in Syria. Apparently he's also relying on the disproven (?) photo op story. There are some general wisdoms in that statement I can fully support - "At home, we should use our military only when requested to do so, on very rare occasions, by state governors." and "The words “Equal Justice Under Law” are carved in the pediment of the United States Supreme Court. This is precisely what protesters are rightly demanding. It is a wholesome and unifying demand—one that all of us should be able to get behind." - for example.
But when he says "We must not be distracted by a small number of lawbreakers." I think he seriously underestimates the scale and scope of the riots, of the property damage, of the casualties, and of the general effects this will have on the strength of the social fabric in the US. His statement of "Keeping public order rests with civilian state and local leaders who best understand their communities and are answerable to them." is all fine and dandy - only it's blatantly obvious that state and local leaders currently
can't maintain public order and safety.
As for his quips about Trump: Trump's far from perfect, sure. But if Trump not playing softball with his opponents and detractors while trying to put the US first means he's a divider and an immature leader rather than a talker who pays lip-service to every pressure group beneath the sky (which is what his predecessors were), then maybe he's exactly what you needed in the first place.
Edit: I greatly respect the guy for his decades of service. Doesn't mean he's infallible, though.
