"Superpower", even if you omit the US and China requires pitting Poland against Russia, South Korea, Israel, Saudi Arabia, Canada, the UK, Germany, etc.
Not in a conflict, I mean - just in terms of measuring their military strength.
Those nations each have a lot going for them, from vast nuclear submarine capabilities, to large technological and financial advantages over their neighbors, to tremendous industrial capacity and very strong intelligence agencies.
Russia's nuke fleet is nothing to ignore. Israel and South Korea's tech over their Arab/Peninsular neighbors is War of the World's level different.
Canada and the UK, even ignoring the US dominance of AUSCANZUKUS/Five Eyes as wealthy Anglophone nations with long histories of being Western powers have the ability to project significant force and be tacitly looked to by the international community as 'good guys' (in a way China or Russia or Brazil simply do not)
It's fashionable to laugh at the Germans, given how presently underequipped and non-aggressive the Bundeswehr is in comparison to the Heer of past regimes, but they're not strangers to the arms industry, they have lots of cash on hand, and any conflict that would involve their national defence would come with 'lead time' (because someone would have to go through Eastern Europe first)
Poland doesn't have those advantages.
They do have really significant economic growth, domestic arms production, and a modernized military. They don't have oodles of money for ramped up defense spending, and they don't have access to an intelligence community like Germany got read in on (and thus became party to a lot of things it's people are uncomfortable with)
But Poland does have NATO membership and does have a mostly Polish people sans unassimilated immigrants, and a brutal recent national history.
That coupled with a greatly improved and improving economic base means they're poised to become a great regional power in the near future like S. Korea.
I'm not saying go invest in Eastern Poland
But I am saying that the złoty will look more and more important, and Poland with it, and a natural outgrowth of their economic improvement and history will be a focus on military improvements.
I just hope we can snag some of them as immigrants before they all decide to stop leaving.
