US Defense Secretary James Mattis said Pentagon is to take back all the weapons it had earlier provided to the Kurdish People’s Protection Units (YPG). But only after defeating ISIS.
Turkey considers YPG to be a terrorist organization and fights them. US consider them to be a good force against ISIS in Syria and support them. Turkey and USA are NATO allies and have tensions because of them. The issue is going to become an internal Alliance problem if Washington doesn’t keep promise as Ankara is really concerned about Kurds being armed with modern weapons.
According to the sources, YPG fighters are not intending to give the weapons back to the United States as they have their own aims in Syria.
