Maybe in Massachusetts, but come down here to the South & Southwest and I imagine you’ll think differently, especially Texas. The Romans were very well drilled and trained, and yes, we have people like that in our present day military, but I don’t see very many of them fighting their neighbors. The Roman legions mostly fought outlanders or slave rebellions, towards whom they had little or no empathy. And if it is so easy to quash a revolt or rebellion, please explain Iraq, the IRA, Afghanistan, Vietnam, the Moros, Chechnia, etc., etc...
Conservatives love to laugh at Massachsuetts and figure it’s a lost cause.
Over this last weekend there was a gun show in the Boston suburbs, and the line to get in the first morning was 200 yards long.
That’s no exaggeration, but a firm figure.
The most brutal and bloody wars in Rome were between fellow Romans. After the Social War, and then the Civil war between Caesar and Pompey, Rome had a civil war so often it became expected.
It was very common for a legion to attack a fellow legion that it had fought side by side with a short time before. There are records of father and son fighting each other on the field.
They followed orders. That is what soldiers do. Expecting that the US military will not kill US citizens is foolish. They have a long history of following orders. Look at the attack on the Bonus army, crowd control with machine guns (Gatling) during the Civil War, and Katrina of you don’t believe me.
