Would the EU allow us to transfer through land to support Lithuania? Poland?
That is the issue with NATO. Does Germany want to die for Poland?
Poland is a full member of NATO, so Germany is obligated to defend Poland.
Since Lithuania is an EU member, the EU could hardly refuse. As for the Germans, they’d probably wring their hands and complain bitterly but allow it. The Moscow paid for SPD would probably prefer a “negotiated” settlement with Poland and the Baltics making all the concessions, but the mainstream are close to fed up with Putin’s and Lukashenko’s antics already. The Bundeswehr would be hard pressed to contribute anything besides a token force.
