Like what? They will give lip service to political freedom, but won't kick out their most important member. Erdogan can carry out a holocaust, and NATO would prefer it over seeing him on team Russia.
I don't think jumping to the conclusion that Erdogan could carry out a holocaust and come out unscathed by NATO is a logical assertion. At some point, another nation will intervene, because Turkey is a fairly major portion of infrastructure in the world. I'm not an expert, or even amazing with politics, so I could be completely wrong, but I accept that. (To each their own opinion, right?)
