The triumphal liberal cosmopolitanism of the 90s is starting to fade in Europe and the US, what's left looks more and more like cynical window dressing for brutal realpolitik. Nationalism, irredentist attitudes, ethnic cleansing and military conflict seem to be very much back on the menu as of late.
I see all of those as negative developments, but it's maybe time to wonder who's living in the past, them or us.
