Indeed, the Turks just struck with a helicopter air strike:
Turkish helicopter gunships attacked abandoned villages inside Iraq on Tuesday, Iraqi officials said, the first such airstrike since border tensions have escalated in recent months.
But there might not be many PKK in Iraq to hit:
Thousands of PKK Kurdish rebels are leaving northern Iraq and crossing into Iran, where they will hide from a threatened Turkish invasion.
Given that Iran has already set the ground rules by striking into Iraq to hit Iran's Kurdish rebels, could Turkish troops go east rather than south?
And would that destabilize Tehran as much as some worry a Turkish attack could destabilize Iraq?
