And now let's imagine what might happen if the US military tried to occupy a country full of guerillas who look like them, dress like them, speak the same language, and share a cultural background.

The US wins on logistics because it has a lot of stuff already built, and anything we need we can build in the US and get it out of the US quickly.

This quickly falls apart in the US if we go civil war on each other. We are technologically fragile. If just a small portion of the people of the US went around shooting electrical distribution, fuel refining and NG compression facilities the US would have one of the worst humanitarian disasters of the last 50 years, maybe longer.

This said, there are a number of countries that would love to see us do this to each other.
