Here, so you get it, as I was a bit wrong: https://www.nato.int/content/dam/nato/webready/documents/fin... - page 3.

Poland spends 4.5% and that is the highest number, the rest are spending much much less.

Tell me again how they're spending more???

By sending stuff and people to Ukraine. But that doesn’t end up in the Nato GDP spendings, because it goes through their governments not NATO.
