Just what is our business in the Black Sea?
Intelligence gathering.
It ain’t for the Ruski’s to determine.
Last time I looked Romania is a NATO member, and we have military bases there. Romania is located on the Black Sea.
Hence US (NATO) aircraft fly there.
Of course Russia views the Black Sea as the Kremlin’s bath tub.
As many who have traveled to Romania can testify, the Romanians love America.
