The Kurds are fond of saying that they have no friends but the mountains. Yet one entity has pushed for their separation from both Iraq and Syria, over many decades.
Israel. The relationship between the two has evolved to the point where Israel is the only voice in the west Asia encouraging rather than decrying the Kurdistans separation from Iraq. Netanyahu first publicly voiced support for an independent Kurdish state in June 2014, as the threat of Daesh was rising. However, that fantasy was blocked by the Iraqi resistances elimination of Daesh ridding the Kurdish contras from Daesh threat.
