The Bosnian War was a terrible  event in recent history, but it's another example of the restless peace that comes when powerful nations impose new borders and no real dialogue takes place between the warring countries.  It's still complicated and volatile.

The boundaries imposed in the Middle East after WWII are the source of trouble there today for the citizens of various countries in the region and for the whole world.  

How unnerving to see Donald Trump's poster up as though he holds hope for the people there.  It would take him a lifetime to understand the history and politics of the Balkans and he probably couldn't be bothered; he's more likely to just do whatever he feels like doing at the moment.  Frightening.
