Why the Obama administration keeps making the same mistakes over and over.
It's been a bad few months for those determined to believe humanity is marching inexorably towards a more peaceful future.
In Iraq, militant extremists so brutal they were disavowed by al Qaeda have captured numerous major cities, leaving behind a trail of mutilated corpses. In Syria, civil war deaths now exceed 150,000, and military momentum has swung back towards the ruthless Assad regime as rival groups of extremist insurgents marginalize moderate rebel forces. In Afghanistan, Taliban forces are resurgent; in Ukraine, a low-level civil war continues. Even the Promised Land has exploded again. So much for the Better Angels.
