IF Russian spies are blowing up mainland US infrastructure, you can expect a massive escalation in Ukraine.

You probably mistook Biden for Scholz.

Germany and other European countries are the contained nuclear war location in case of an escalation. It is easy to support all sorts of things from another continent.

De Gaulle also did not trust the U.S. precisely for this reason and chose to build nuclear weapons and avoid being under the NATO command structure.

I'm not saying withholding certain types of heavy weapons is good or bad, I was just responding to the person saying that Biden doesn't want these weapons to be delivered, which seemed a bit misguided.
