Kurds Number 1; Jihadists Number 10.
All joking aside; the Kurds and the Assad forces should adopt a “you leave me alone, I’ll leave you alone” approach. I know that will be hard for them to do, but then they can save their fire for the Jihadists.
It would be fierce fighting indeed, because the al-Nasra front has massacred Kurdish villages in northern Syria. It is all-out war between them and the Kurds.
