Never going to happen. Even if somehow the AfD were to form a government they wouldn’t do it. The financial interests of the big German bourgeoisie are too tied up in the EU project. Germany is not in the same position as the UK was to be able to at least somewhat disentangle itself from the EU, and Brexit was already a huge clusterfuck, but at least the UK still had its own currency. Germany has no alternative to the EU, and also it profits immensely from exploiting the peripheral EU nations. And the US would never allow it. The EU is too valuable a tool for the Washington neocons and their atlanticist acolytes in Brussels to control Europe. This is empty populist rhetoric for the AfD’s petty bourgeois base. They talk a big game but at the end of the day i guarantee you they are also beholden to the US.

The most they would do if they got into power is pull the same bait and switch that Italy’s fascists did. They will implement all of the xenophobic policies and none of the populist ones they ran on, and they will crank up the neoliberalism while staying loyal NATO imperialist footsoldiers in foreign policy.
