Somewhere along the way the US made a commitment so I guess we’re sticking to it.
The commitment is based on many lives lost as we helped SDF (Kurds and Arabs) fight to end ISIS Terrorists.
Now we witness our NATO ally (sarcasm) Turkey attacking Kurds in N. Syria with the help of ISIS and al Qaeda. Russia has allowed this, by opening the airspace to Turkey. Otherwise, Turkey would never have succeeded like they have. And it has not been fast. This has been going on 2 months.
Turkey is leveling whole villages and intends to resettle foreign elements where they kill those who have peacefully live in Efrin avoiding the war. And Turks are bombing civilian targets with impunity.
