I really don't get it. Russians are trying to conquer Ukraine and they are nowhere near it. Ukraine is armed with scraps from old Soviet stocks which are by now almost completely out, scraps from literately Western scrapyards whereas they are getting equipment that becomes surplus when the West upgrades, and whatever they could buy from Aliexpress and glue together.
Ukraine is an incredibly, systemically corrupt country where people steal from their own family and from themselves (due to cultural reasons to a large extent), where half the people don't speak their native language, and a good third is confused as to what their nationality was. A country that was the Europe's topmost shithole (after Moldova) ever since 1991, with deeply dilapidated infrastructure, defunct industry sold for scrap metal in the 1990s, and famously prevailng cynical, nihilist mindset. It is just like Russia but a lot more divided, and without oil.
Only thing that plays in favour of Ukrainians is that they have by necessity become tough people living through this hell for 35 years.
If Putin can't defeat Ukraine, idk how is he planning to go against Poland, or Finland.
