AfD's Extremism Isolates It From European Far-Right Allies as German Politics Fractures

Friedrich Merz arrived at the chancellery last year with a mandate that looked straightforward on paper: lead Germany's largest center-right bloc, the CDU/CSU, through a fractured parliament and form a governing coalition. The math seemed workable. But nine months into his tenure, the ground has shifted beneath him in ways that expose a deeper fracture in German politics than anyone anticipated.

The immediate problem is numerical. The CDU/CSU, which Merz chairs, has seen its support collapse to 19 percent—a historic low for the bloc. That figure alone would be alarming for any chancellor. But the real crisis is structural. Merz cannot simply turn to the far-right Alternative for Germany, or AfD, because the AfD has become so ideologically extreme that it has isolated itself even from other right-wing parties across Europe who might otherwise be natural allies. The AfD's radicalism is pushing away potential partners, not drawing them in.

This creates a paradox at the heart of German governance. The traditional strategy for containing the AfD—a "firewall" approach in which all other parties refuse to work with it—has held for years. But that firewall was always premised on a functioning political center. With the CDU/CSU hemorrhaging support and no viable coalition partners willing to work with the AfD, Merz faces a narrowing set of options. He must build a government without the largest bloc's natural allies and without the votes that would make governing simple.

The AfD's isolation from European far-right movements is telling. Across the continent, right-wing parties have learned to soften their edges, to present themselves as defenders of national interest rather than as ideological radicals. They have built networks, made strategic alliances, and positioned themselves as potential governing partners. The AfD, by contrast, has moved in the opposite direction. Its positions have hardened. Its rhetoric has become more inflammatory. Other far-right parties, watching from Budapest to Rome, have concluded that association with the AfD carries too much risk. The party has become a pariah even among those who share its general worldview.

Merz's scramble for support reflects this reality. He cannot rely on the AfD. The Greens, the Social Democrats, and the Free Democrats all represent different political traditions and constituencies. Cobbling together a coalition from these fragments requires negotiation, compromise, and the kind of patient coalition-building that does not come naturally to a chancellor facing record-low approval ratings. Every day that passes without a stable government deepens the sense that German politics is adrift.

What emerges from this moment is a question about the nature of the firewall itself. For years, German political elites treated the AfD as an external threat to be contained. But containment only works if the center holds. With the CDU/CSU at 19 percent and no clear path to a majority, the firewall is no longer a choice—it is a necessity born of weakness, not strength. German parties are not isolating the AfD because they have decided it is dangerous; they are isolating it because they have no other option. That distinction matters. It suggests that the political architecture that has held Germany together since 2015 may be reaching the end of its useful life. What replaces it remains unclear.
