"People trying to credit US air strikes with the Kurdish fighters turning the tide in Kobani against ISIS ignore a crucial fact: The US spent billions of dollars training the Iraqi Army for nearly a decade, providing them with tanks, artillery, heavy weapons. And yet this army completely collapsed when ISIS took the second largest city in Iraq(Mosul), in spite of there being a garrison of 50,000 Iraqi Army soldiers vs. 1,500 ISIS fighters. All the weapons in the world don’t matter if you have soldiers who are not motivated to fight.
No, what was different is that the Kurds of the YPG/YPJ, in spite of being outgunned, outnumbered, and being under attack by forces backed by a NATO power(Turkey), still had things the Iraqi Army didn’t. They had organization, discipline, determination and the WILL to fight to the last man and woman if necessary. And something to fight FOR- the socialist oriented, pro-womens liberation, anti-sectarian liberated area of Rojava, not a corrupt, rotting, sectarian infested US-backed client state. That is what was decisive here.
