Remember Ayn Issa: Turkish airstrike open the door to ISIS resurgence

Now it seems this ugly, recent history is repeating itself. A
Turkish invasion will not only mean the chaos of air strikes and
subsequent opportunities for ISIS cell members to spread further
havoc. It will mean creating new swathes of territory for ISIS to
operate in. It will mean humanitarian disaster as Turkey strikes
power stations, hospitals and other vital infrastructure, creating
the perfect conditions for ISIS to make back the ground which the
Kurds and their local allies wrested from them on behalf of the
world across many years of bitter warfare.
