The West does? Really? Here I tought we were too busy fellating the Sultan of Turkey, the grand Erdogan to actually give a flying f*ck about the Kurds (as long as they're not useful idiots).
Yes, Israel for one was very happy with the Kurdish independence referendum. There are parts of the Greater Kurdistan in Iran for instance, not to mention how much some Kurdish Iranians cheered when they simply heard about the referendum. You think that at this point, the west or more specifically, America and its allies aren't interested in a civil war in Iran? Think again. Iran together with North Korea are on top of the wanted list of the U.S government and there is no easier way to dismantle a regime by the means of civil war. Why send troops when you can cause a chaos and let people fight themselves? Syria, Libya, Yugoslavia, Iran, Egypt and many more countries have experienced this one way or another.
