Reportedly German-made Marder IVFs have been spotted in Russia's Kursk region [being targeted by Russian forces].
Has this provoked any backlash in Germany, like parliamentary inquiries etc., given Germany's more reluctant approach toward arming the Ukrainians with weapons that can reach Russia (like cruise missiles)?
Someone was asking in comments for more motivation for the Q. Only last year [and a half ago] Time was writing:
Berlin’s reluctance to heed Ukrainian calls for battle tanks demonstrates the limits of Zeitenwende and Germany’s deep divisions over what kind of military power it should be, if indeed it ought to be one at all. But those within the German government offer a different interpretation: one not of indecision, but prudence, and a desire to be seen as keeping pace with allies rather than leading them.
“There are very good purely military reasons to send these kinds of weapons to Ukraine, for sure,” says Nils Schmid, the foreign policy spokesperson for Scholz’s Social Democrats in the German Bundestag. But if “something turns ugly and if, against all odds and all expectations, the war spreads, the responsibility will fall fully on the shoulders of Scholz and [U.S. President Joe] Biden and [French President Emmanuel] Macron.”
Also Euronews says that even the Biden administration only gave Ukraine permission to use American weapons in Russia this spring "for the limited purpose of defending Kharkiv". And this Kursk incursion is about 200km away from there. (Typically, Germany didn't veer too much from the US position.)
