I suspect the Poles would love that. As I recall, we did some training exercises with them last summer.

However, it would be ridiculously expensive to move infrastructure from Germany. Plus, tactically, they are further back from the front lines (or what would be the front lines).

Yes, your data seems to be pretty good. I found this chart useful, even if it's from last July: reuters.com - Scope polands spending spree focus NATO ups defence goal

As of July, 11 are exceeding their targets. Which, as someone point out, they don't owe NATO. It's not like a tax, there is no revenue agency. It's a target or goal. BTW, I earlier misspoke. TWO nations have seen a drop, Italy and Croatia. The rest have seen an increase towards target (including Germany). No surprise, the countries feeling most threatened are generally the ones with the biggest increases. Thanks, Vlad!
