The expert explained why Turkey will not abandon the s-400

Turkey does not sell s-400 to the United States because it questions national security is more important than the political situation, said RIA Novosti Director of the Center for analysis of world arms trade (TSAMTO) Igor Korotchenko.

Earlier, Republican Senator John Thune has offered to buy Russian anti-aircraft missile system s-400 from Turkey to resolve differences between Washington and Ankara.

The expert noted that the purchase of a NATO country, Russian air defense systems instead of the American Patriot is a severe reputation loss of the US and its "defense." According to Korotchenko, the determination of President Tayyip Erdogan to bring the deal to purchase the s-400 until the end connected with lessons which the Turkish leader made after the failed coup of 2016.

"Erdogan remembers that the initiators of the coup in Turkey was a separate officers and generals of the Turkish air force, behind them was the US intelligence services. Then the Turkish President miraculously survived because the rebels wanted to destroy it, so it control of the airspace, the Russian air defense is a major factor of national security", - said the Agency interlocutor.

Deliveries of the newest Russian air defense systems s-400, which caused a crisis in Turkey's relations with the United States, began in mid-July 2019. Washington has demanded to cancel the transaction and return to purchase American complexes Patriot, threatening to delay or even cancel the sale of Turkey's newest F-35 fighter, as well as to introduce restrictive measures. Ankara has refused to compromise and continued negotiations on additional batch of s-400.

In fact, the United States have fulfilled only part of the threats regarding the F-35 and other sanctions, despite the fact that by law they have to be entered not used.
