Exactly. This is what happened to Sparta. Spartan's lived in constant fear of the helots, their slaves until one day, the helots did destroy Sparta. In our case, empire began away from our shores and we were kept in a propaganda haze unaware of our government's excess abroad. Slowly but surely, the snake has been eating itself and today, the evils of the American empire are lapping on our own shores.
Nineteen50, you are right. Trump needs to protect the empire from all the enemies laid to waste abroad, hundreds of thousands in Iraq alone. Enemies who look Mexican but are not, so to be sure exclude them all before they exact their revenge.
This is why Syria, with Putin's blessing, has embarked on a systematic purge . . . we'll be doing the same here if Trump is allowed to continue his rampage.
