As for Germany, the country has given some, but the chancellor is reluctant, because he actually seems to fear Russia (every weapon system needed months of convincing him), the former (lol) ordoliberal finance minister refused take out loans due to a austerity program called 'debt brake' and the powerful opposition party sued the government's household and won, so suddenly 66 Bn disappeared which combined with extreme austerity enforced by a 10 percent party in coalition largely limited defense spending.
TL:DR Austerity wins over Ukraine (or anything) big time.
