Thank you for (1). I hope it is true. One of my concerns is that the US military is a volunteer force, and may differ from the military in other nations.
As for (2), US wars, generally speaking, may not provide examples of what the US is capable of. What the US military does and what it has the capability to do are different things. For example, you could also say that the US was defeated in Somalia, Iraq, and Afghanistan. However, one must consider that the "scorched earth" approach with massive, intentional killing of civilians is one the US has mostly avoided, at least since WWII and Japan. I am assuming that if there were a massive and violent domestic revolt, the US government might stop at nothing to control it. That is a worst case scenario, and my assumption could be wrong.
