Unless they pull off some kind of paramilitary overthrow of the German government (and last time I checked their co-leaders didn’t have an army of brownshirts to do their bidding) I cannot see Alternative fur Deutschland taking power in Germany. They actually lost vote share and support from other far right European parties when they spouted borderline Nazi views recently.
Reassemblement National on the other hand… Macron was stupid to call a snap parliamentary election, and if Marine Le Pen can make it to 2027 without being driven out by political scandal, she’ll probably be the next French President.
