Believe me, I myself are fully aware of it, and also am not satisfied with the slow reaction of our government
Yet we should acknowledge that actually a lot of things are done - financial aid, medical help, at least waiving through every order they place for German weaponry with manufacturers. Bundeswehr also did send some stuff, albeit I understand the unhappiness about this, as this is really not going well. But to be honest I don't think this is much about Ukraine itself, but more due to the horrible state of the Bundeswehr. Sadly it's a long time since we had a competent minister of defence
Nonetheless I think it makes sense to talk about how Ukraine is perceived in Germany to understand reasons for this. And that isn't very positive at the moment.
Yes, it is no surprise that those politicians (like minister of economy Robert Habeck) that actually act in this time to help Ukraine rise a lot in popularity, when you see how most Germans want that. Yet I think that support could be bigger if Ukraine acted smarter towards Germany.
