Russia's been gunning for that warm water port since Peter the Great and they will not stop until they get one.
The Russian Quest for Warm Water Ports
By opening the Syrian-Mediterranean front in 2015, Russia bypassed the whole military network that NATO and the United States had placed along the Russian Federation’s Western land borders.
Peter the Great was the ruler of a landlocked nation. The Baltic was practically a Swedish lake and the Black Sea belongpd entirely to the Turks. For nearly two hundred years the policy of obtaining, maintaining, and increasing a seaboard has been consistently followed. If that policy was inaugurated by Peter the Great, it was nevertheless absolutely due to the operation of irresistible natural forces.
A great nation must seek a seaboard corresponding in extent to its needs, and Russia could no more be restrained in her seaward expansion than could the United States in overflowing the Rocky Mountains in their march to the Pacific. The policy thus forced upon Russia by the conditions of her being has involved many wars and great sacrifices."
