There is no question that the Americans will continue to try to create mischief around the world, “touching” vulnerable, exploitable countries, for as long as they can. But there is another question that deserves to be asked: Do the Americans “touch” themselves? Because if they do, then the next candidate for extreme makeover into a bombed-out wasteland might be the United States itself. Let's consider this option.
...And that's where things get interesting. Because, you see, if you shoot at, imprison, and otherwise abuse a defenseless civilian population long enough, what you get in response is an armed insurgency. The place insurgencies are easiest to organize is in prison. For instance, ISIS, or the Islamic Caliphate, was masterminded by people who had previously worked for Saddam Hussein, while they were imprisoned by the Americans. They took this opportunity to work out an efficient organizational structure and, upon release, found each other and got down to work. Having a third of young American blacks locked up gives them all the opportunity they need to organize an effective insurgency.
To be effective, an insurgency needs lots of weapons. Here, again, there is a procedure for acquiring military technology that has become almost routine. What weapons are being used by ISIS? Why, of course, American ones, which the Americans provided to the regime in Baghdad, and which ISIS took as trophies when the Iraqi army refused to fight and ran away. And what weapons are being used by the Houthi rebels in Yemen? Why, of course, the American ones, which the Americans provided to the now overthrown pro-American regime there. And what are some of the weapons being used by the Syrian regime of Bashar Assad? Why, of course, American ones, sold to them by the Ukrainian government, which got them from the Americans. There is a pattern here: it seems that whenever Americans arm, train and equip an army, that army stands a really big chance of simply melting away, with the weapons falling into the hands of those who want to use them against American interests. It is hard to see why this same pattern wouldn't hold once the US places much of itself under military occupation.
This is fundamentally the answer to the 'how much ammo to stockpile in the event of SHTF?' question. Enough to get more off of the unmotivated slave armies sent to quell the rebellion. People aren't yet thinking of the blowback that happens from the war coming home, but they'd better be. People don't take kindly to being militarialy occupied for long.
