In April, the Pentagon claimed that Turkey's adoption of Russian missile could cause security risk on F-35 jets and NATO defense system, and threatened to suspend the sale of F-35 jets to Turkey unless it scraps the S-400 deal.However, Turkey has refused to bow to U.S. pressure, insisting that choosing which equipment to purchase is a matter of national sovereignty and does not target any third country.
