I agree with you 100%. To my knowledge, there hasn't been any comprehensive polling in regard to the German populace's view on the delivery of Leo tanks etc. as of yet.

People are scared of the escalation any major deliveries of arms may cause. They are scared of a full on NATO-Russian war, which is understandable. They criticise NATO's eastward expansion as well as the USA's imperialist/militarist stance now and in the past. They shout "peace" but ignore Russia's utter disregard toward Ukraine's right to even exist. They are apologists and choose to ignore that Russia basically wants to eradicate Ukraine as a culture / sovereign nation.

To many, the situation is a dilemma, which is why they draw historical comparisons to US American illegitimate wars of the past.
