history likes repeating itself. tolerance is a loaded term but intrinsically it is human nature to fight when one set of ideals clash with another. most of us just get to sit on the fence or cry from our white towers which one is more morally correct.
Russia is not targeting infrastructure which implies they are not wanting to destroy Ukraine but rather assimilate Ukraine back into Soviet Russia.
polls in Russia show that around 77% of the population wants a return to Soviet Russia, this is about their pride to get back what the West stripped them of and they will fight for it.
it is also indicative of the failings of western values, which are being eroded internally by cultural hedonism. Russia and China have now been emboldened and the West needs to be prepared to fight or will just collapse. Putin is no Adolf Hitler or Lenin/Stalin, he is just a lap dog that scares the west
