Measured by their GDP, they are at the back.

Not really. They’re at 10th place with 1.2% and the only countries in front are small countries with a weaker economy, which benefit much more from GDP measurements. For comparison, the UK is at 20th place with 0.5%, the US at 29th and France at 30th place, both with 0.3% each, Italy at 34th place with not even 0.2%.

The German government acts half-heartedly due to a long standing appeasement policy towards Ruzzia by the ruling social democratic party.

Alright? If Germany acts halfheartedly because of your disinformation, what’s your excuse for literally everyone else being so much worse then? If “appeasement Germany” is one of the greatest supporters of Ukraine, then that paints an even darker image for all the other countries, no? Like, what does this say about the West? That they’re all Russian puppets? I’m really curious about how you’re rationalizing this with how you think about Germany.

They are not all-in which they should be.

Germany simply does not have much actual military gear, because after the cold war ended, everyone in Europe, especially the countries to the east of it, wanted Germany to demilitarize so that they’re not a threat again. Like, I’m sorry but you cannot expect a country to constantly flip-flop on their military. Changes like these are not just expensive but also take a lot of time. And just to be clear, by definition no one but Ukraine is “all-in”.
