The US has a lot of money and there are a shit ton of billionaires trying to get the US government to give them even more money. The far right is very willing to do that, so they got what they wanted with a Trump victory. Now they go for the next targets and Germany is the obvious one. Third largest economy in the world, so a lot of money and elections are soon. However this is not only going to be a German issue, but will effect other European countries as well.

The way to end this is to push the far right out of governments everywhere and to make sure they do not get more power. That means good democratic government and actually cracking down on the far right, when they commit crimes. For the US that was clearly the failure of putting Trump behind bars and for Germany it is not banning the AFD right now. That being said, all other countries also have to do that as well.
