We have around 800 bases scattered around the world as best as I can see they have 2 or 3.
Freaking out over them having a worn out port facility in Syria is really kinda funny.
It has been a long standing strategic interest of the United States and the Western European allies to contain Russian (Soviet) naval power by controlling the Dardanelles and thereby limiting their access to a warm water port. It is that goal that has primarily kept both Greece and Turkey under our influence.
With that, during peacetime, we grant Russia access thought the Dardanelles, but when hostilities arise, we have the ability to control access in and out of the Black Sea.
Good thing to see Russia and us starting to work together. We are natural allies
