Every city should be able to choose what country it belongs to, periodically. These nationalities are making people go crazy killing each other for a flag to fly over a specific territory. Most of the local populations are radicalized using mass media or government schools. It’s sad to see.
My developers are in Ukraine and Russia and I attended one of their weddings in Chernovtsy a few years ago. We all work together and we don’t want to kill each other. I’m in the USA. The vast majority regular people would not want their country killing anyone in their name. They’re just fed propaganda about how benign their country’s actions are, and how bad the “other guys” are.
Take Crimea for example. It is majority Russian because Stalin deported the vast majority of Crimean Tatars because many of their men fought against USSR in WW2. Ethnic cleansing. Then Khustchev just gifted Crimea to Ukraine for no apparent reason. But when they had a referendum they voted to rejoin Russia. In an ideal world, no one would give a shit what flag flies over Crimea. They could vote every 4 years to be 80% Russian and 20% Ukranian. By removing the need to choose a discrete variable, you’d eliminate almost all conflicts between separatists and imperialists. Catalonia vs Spain. Basques vs France. Kurds vs Turkey. But no. People need to fight for what flag flies over that territory…
