Even if you do not understand that, but if somebody else asks me for help, even
demands me to help, and leaves no opporutnity unused to lecture me why I am obligated to help (in his view) - and then, while I comply with his demands, starts blowing up my car or hacks my bank account or in any other way strikes at me, I take that a little bit personal and do not just wash it off my mental noteboard.
You may balk, justified or not - but you certainly do not bite the hand
you expect to feed you.
Germany is now the second biggest military donator after the United States. And, to my best knowledge, different to parts of the American deliveries, the German deliveries are all donated - not in parts sold. In parts systems like recently another Iris-T get delivered with prioprity to Ukraine that even do not go to the Bundeswehr.

Again: you do not turn against those whom you ask for help, demand you to help, lecture to help you.
Actually thats quite simple, obvious.
