I'm not sure there is causation here. Far-right ultra-nationalistic movements are gaining speed in many places in the world. I think there are many factors at play, one being that we get further and further away from WW2 and people forget how bad it can get (especially here in Europe). Only the military and very old people in the west now know what a real war feels like. On top of that there's general social unrest and increased inequalities (the infamous 1%), software eating the world etc...
I do think that white supremacy, fascism and nazism was really a lot more fringe even only 10 years ago, it wasn't just under-reported.
