According to the above link, the Russian S-300 missile defense system is being used by three NATO countries: Greece, Bulgaria, and Slovakia.
According to the above link, the USA is welcoming Greece's decision to purchase F-35.
According to the above link, the USA is worried that Turkey using S-400 and F-35 at the same time would give Russia the opportunity to collect data on F-35.
According to the above link, the USA is soft in India for buying S-400.
Now, I have two questions here:
- Since, Turkey is officially expelled from the F-35 project, why has the USA sanctioned Turkey for S-400?
- Why is the same attitude as Turkey is not visible in the case of Greece and India by the USA?
