From what can be gathered the resolutions was met with a lot of public support just as how the Bundestag reacted to it.
First of all the speech by Scholz was good, like career defining good. It touched on all the important points. It made a clear distinction between Putin and the Russian people, which was incredibly important given the large Russian community living in Germany (more than 3 million) and while it touched on the security aspect of increasing military spending and sending weapons in war areas it emphasised the sense of responsibility of it far more.
The widespread support for it does not really come from a place of fear and worry imo. The number of people who fear a direct attack on German soil is still really low and there are good arguments for that (situated in the heart of Europe, surrounded by allies, high economical importance etc.), but the sense of responsibilty to contribute to defending its values more has definitively grown the last days. The Ukraine war hits far closer to home than other recent wars because a lot of people know people who are directly involved here. The Syrian refugee crisis also played a part in a shift of perspective as it brought the consequenses of war at our door step.
If there is something to be said about Germans it is that if they feel the need to open their wallets for an important cause they are willing to share their wealth and do it by spending big. What I do not see is a run to enlist in the army and take up arms as the generally anti militaristic stance still remains. The Bundeswehr will rather transform into a far better run machine with a high technological standart, supported by a potent arms industry at home. I also do not see it shifting their focus away from a thouroughly defensive force, far better equipped to watch the European borders and the other nations back than to intervene directly elsewhere.
