World War III technical trials: in an interview with Sputnik News (a rather pro-government Russian site), the head of the Turkish Intelligence Department Hakki Pekin condemned the recent shooting down of the Russian Sukhoi24 bomber by the Turkish air force, calling it a "big mistake".
Pekin foresees big problems from now on, and a very hard and well organized response.
“Aside from the cancellation of official visits and probable economic sanctions, Russia is placing its Iskander missile systems in Kaliningrad. And it has very strong potential in this field."
Putin would be in possession of information on the sale of oil by ISIS through Turkish territory, and these would be the reasons for recent 'close' patrolling activities with respect to the borders of Erdogan's country. For this reason, Russian Defense Minister Sergey Shoygu tweeted the decision to use the S-400 missile system, definitely one of the most fearsome in the world, at the air base near Latakia, close to the Syrian coast.
To give you an idea, this is the most advanced missile system in Russian possession, a system capable of hitting targets up to 250km within the Turkish borders, located just 50km from the border.
The shooting down of the Russian aircraft is considered by Foreign Minister Lavrov to be a "premeditated provocation".
Everything suggests that the tension will not rise rapidly, but that it will rise massively and constantly.
