The whole world is amazed how Russia managed to conduct swift and efficient military actions in Syria. King Salman is one of those people amazed by Russian determination.
According to reports, he is interested in discussing Russian counterterrorism campaign in Moscow. It was revealed that he is interested to establish cooperation with Russia.
Even though Saudi Arabia is one of the main allies of the US, they are also looking forward to establishing better relations with Russia.
As Obama will soon be retired from his position, there is no one left in the US who will work for the interests of Saudi Arabia. That is also one of the reasons this country is turning towards alliance with Russia.
Saudi Arabia is also concerned over the Iranian-Russian alliance. Therefore, the best strategy is to join Russia. By doing this, King Salman hopes to have more influence on Iran with regard to Yemen, Iraq and Syria.
