A century ago, Polish and Ukrainian nationalists fought a brutal war against each other, where at least 50,000 died. Now they are allies. Let's hope history continues to follow this pattern, and we put #nationalism to rest. Let people be people, and respect their culture, language, religion, and democracy wherever people happen to live. Central Europe always was and always will be multi-ethnic.
