WHO CARES?
The Israelis have made some friendly relationships with the Kurds in northern Iraq, and should go to great lengths to cultivate this relationship.
A very tangible way to do this is to encourage and support the Kurdish effort to create a “greater Kurdistan”, because there are many advantages to doing so.
There are Kurdish lands in Syria, Turkey, and Iran. With the fall of Assad, there might be a window of opportunity for Kurdish Syria to split off and join with Iraqi Kurdistan.
The same situation also applies to Iranian Kurdistan. Less so with Turkey. However, as an autonomous part of Iraq, Kurdistan is close to having the momentum it needs to split from Iraq and form a nation of Kurdistan.
Were Israel to aid with the above in strategic ways, the far more reasonable Kurds might decide that an open alliance with Israel, while it would drive the Arabs and the Persians nuts, would be the best way for them to stay secure and advance in the world.
