You just "hand wave away" gaining territory the size of the 2nd biggest country in Europe after Russia, Trillions in resources and 40 million people (a 30% increase in "Russian" population). I think you may be slightly undervaluing these things lol.
And then I just don't really understand your general point which seems to be that because you believe Russia could not successfully defeat Europe/Poland that they are not more threatening than they were 10 years ago?
- Russia will have gained a huge amount of combat experience.
- Russia will also have learned from fighting against a force using NATO equipment.
- Russia will have gained the immense wealth of Ukraine's natural resources.
- Russia will have increased their population by about 30% (+/- based on refugee point below)
- Russia will have basically doubled the size of their border with Poland (counting Belarus as part of Russia because why not)
- Russia will have added borders with 4 more European countries (Slovakia, Hungary, Romania, Moldova)
- Russia has likely rooted out some of the corruption that plagued the military before/during this invasion as it would have become more apparent.
- Russia will have built up domestic production of weapons as much as they can (taking sanctions into account)
- Russia will have been emboldened by its "success" in conquering Ukraine.
- Russia will have seen how slow/scared the West was to respond to their invasion and encourage more "asymmetric" warfare in preparation for the next country (aka "the price of eggs are too high, we can't afford to save <insert country with Russian border here>)
- Russia will VERY likely have increased the amount of Ukrainian refugees to the rest of Europe by 100s of 1000s, possibly even millions. Further stretching the resources of those countries and feeding into the previous point in regards to the cost of intervening "next time".
All this, combined with a US President openly making disparaging remarks about NATO, but you think Europe should not be more worried about Russia than in 2015?
Ok...
