Russia is back. President Vladimir Putin wants the world to acknowledge that Russia remains a global power. He is making his stand in Syria.
The Soviet Union acquired the Tardus Naval Port in Syria in 1971 without any real purpose for it. With their ships welcomed in Algeria, Cuba or Vietnam, Tardus was too insignificant to be developed. After the collapse of the Soviet Union, Russia lacked the funds to spend on the base and no reason to invest in it.
The Russian return to the Middle East brought them first to where the Soviet Union had had its closest ties. Libya had been a major buyer of arms and many of the military officers had studied in the Soviet Union. Russia was no longer a global power, but it could be used by the Libyans as a counter force to block domination by the United States and Europeans.
