Germans have the ability to provide much more deadly weaponry to the Ukrainians - it is just a matter of intent.
Piss them off. Piss everybody off.
Pay the consequences.
Putin started this.
Putin has violated the laws of war, and returned savagery to Europe. Europe in turn, will likely return to savagery, given enough pain.
Putin gravely miscalculated Ukrainian will to fight. Miscalculating NATO’s will would be truly historic. But typically Putin.
Deadly weapons are going to return to Germany. It is only a matter of time before the airliner is downed by Stinger. And no weapons are going to dramatically change the situation to Ukraine’s favor.
Putin definitely didn’t start an economic war with Europe, Germany said is going to “crush Russia”.
Except Europe has little of what Russia needs, and Russia has energy, fertilizers and food.
At the very least Russia can make the Germans very poor people. Their factories are going to stop without gas, at max Russia is going to make them starve.
Why not? They should blame their politicians.

What you are proposing is national suicide—for Germany.
Shooting yourself in the knee to protest the high school bully is just dumb.
Nobody wants to be the crash test dummy.
