Factions with aspirations toward fascism have always existed in Europe. The founding sentiment of the nascent EU (the Common Market, or "The Six") was to promote such strong cooperation among nations that fascism could never again take over. The ground rules are human rights, democracy and the rule of law. The current far-right faction in Italy, no matter what their fascistic inclinations are, either fully abide by those tenets or Italy leaves the EU. That is not going to happen. There are and there always will be fascist rumblings. It's beholden on democratic governments in Europe to understand where they come from. The easiest targets for fascists are the disaffected and the disadvantaged in society. If governments prioritise reducing the gap between rich and poor and making society more equal and fair, those rumblings will be all we'll get. I can't see it being any different in the US, but your first priority is to get off your arses and put Trump behind bars.
