Mr. Kerry, the YPG does not do tragedies! It was created for victories.
An excerpt from, "The War Nerd: Nobody could have predicted Islamic State’s retreat from Kobane (except me)" by Gary Brecher, Pando Daily, October 16, 2014:
If you only read one story about what happened in Kobane, read this battle-journal kept by Heysam Mislim, a Kurdish journalist who decided to stay in the town through the siege.
What he describes is just plain heroic, and it tallies with what I saw of the phlegmatic, stoic Kurdish people in Suli. They don’t make much of a fuss about things, which is unusual in this part of the world, which could be called “The Yelling Crescent.” They don’t yell, the Kurds–but they don’t panic, either. And they held on, expecting very little from their ostensible allies—and they weren’t disappointed in that expectation, either—and waiting until the ammunition ran out, or IS brought in another batch of Chechens, Tunisians, or Iraqis too numerous to be stopped. They knew very well what would become of them when that happened. But as often happens when a force like IS cultivates a rep for insane brutality, that meant that negotiation and surrender was impossible anyway. No one was gonna be spared. There was no choice. They just fought on.
