Were doing what we can. I wouldn't call it propaganda.
Please also consider each country GDP. Everyone have limited resources. Poland GDP is 5 times smaller than Germany or Japan and 36 times smaller than US
The US also is kind of built up to be able to almost single handedly be NATO. Our defensive strategies involve using EU countries as bases. We have a vastly different goal with our military stockpiles. (Other than making defense contractors money I mean.)
On the source website there is quite a bit more. The EU stuff is funded by a share of approximately .2 % of GDP by all EU members in addition to their individual aid.
It's an old comic dude. Also you're missing the joke as well as any historical context.
Poland has been through the wringer for centuries and even ceased existing for a while. Having some issues and hating Russia are some of the least unlikely results.
It probably swings back toward the scenario depicted if you divide the amount given by the total amount that those countries have available to give, but yeah, good to keep real figures in mind while we have our fun.
