The EU is a good start

The nation state largely solved the problem of almost-identical tribes fighting each other over microscopic differences and instead raised identity to a higher level. Similarly, the development of the EU and of other trans-national governance has solved violent nationalism and is raising identity again - from individual nationalisms to that of Europeans. Surely, as humanity progresses, we will eventually reach the widespread acceptance of the identity that corresponds most closely with reality. We are one people, one human family, sharing one small and finite planet. THAT is our REAL and most important identity. Because the truth is that we're NOT different and we're NOT separate. And the sooner the 'official world' reflects that, the better. The EU is a good start.
