Agree but NATO is integrated deeply into their early warning and other systems. Greece and few others did have s300 but Turkey is on a different trust level. This is more to do with them squeezing Russians apart from compromising few technical aspects.
Turkey is NATO, so different discomfort to US than India or non nato. India carries more weight every year and Turkey is on downslide by any parameter. India is the only counter to China and US can;t be rash with India without being stupid.
