APPLEBAUM: Russia's war in Ukraine is sometimes described, including recently by American Vice President, as if it were nothing more than territorial dispute, kind of scuffle over lines on map.
But when Russia denies that Ukraine is a real nation, builds concentration camps on Ukrainian territory, bans Ukrainian language and systematically arrests mayors, teachers, journalists, and priests, then Russia is also attacking Europe that was built after 1945, Europe whose borders are not supposed to be changed by force.
Russia invaded Ukraine not only to destroy Ukraine but also to prove that treaties are meaningless, alliances are weak, and brute force still decides fate of nations.
By waging imperial war of conquest, Russia seeks to undermine Europe's post-imperial order.
