Great point here. No one can, with any degree of accuracy, say how America and the world will look in a decade. Too many unknowns. The best you can do is attempt to use history as a guideline for what can possibly happen and how we all should react to the changes we will have to deal with. If you told Hitler in the summer of '33 that by the summer of '43 his cities would be getting bombed day and night he would not have believed it. Americans especially would not have believed their boys were the ones doing much of the heavy lifting of sending bombers over the Reich.
Again all you can do is prepare and attempt to anticipate changes. The only thing I know for sure is that fascism does not work in the long haul. How long that is I do not know, but I do know it will fail. You just hope that America and the rest of the countries on this planet haven't all gone to war again by the time it does fail.
