This and instead of working with Turkey who is a legitimate partner in fight against terror, US decided to arm the very terrorists whom they listed in their own terrorists list to utilize in the region. In response to Turkey’s objections in a serious announcement US said “look these guys are not the same guys as PKK, they call themselves a different name PYD/YPG/SDF whatever” even though they use the same flag, same leaders, same ideology, same figthers and see Turkey as the enemy. In the coming years Turkey’s NATO membership and US relations is gonna get more and more strained.
