If there is an uprising at some point of the American populace it won't be because of war (Our military is not being defeated in any conventional warfare even with TFG at the controls.) or because people suddenly decided that we should be kind to immigrants. It will be part of the same reason Mussolini was sent packing and that's when the population starts to not have access to the food it needs just to survive. That could be a lengthy wait even with millions of people eventually being sent out of the US who prop up so much of the harvesting of fruits and vegetables we eat daily. When that happens, you'll see a collapse and all you can hope for is a new man or woman in power that brings democracy back.
It's easy to say these things, but how each country handles a situation like this is different. Right now we're handling it, to be kind, poorly. I don't foresee a civil war, but food scarcity is as big a motivating factor for regime overthrows as one that has awful human rights abuses. It took Italy 20 years, a dwindling food supply and Allied bombing raids to get Il Duce kicked to the curb. We start to see millions of hungry Americans that aren't used to 3rd World food conditions and all bets are off on what they do to rectify a lack of food.
