Many years ago the US Navy was invited into Bahrain as a docking facility for Naval ships and to show the flag long before there was any bullshit going on there.
Bahrain was a fairly poor country mostly dealing in Pearls then and was just starting to make millions [before billions] or dollars thru the export of Saudi/Aramco oil loading facilities.
Then there was all of the oil support co.s that moved in there doing business with the other countrys around the Arabian Gulf that they figured did need the protection afforded to American big business doing nasty shit on foreign soil.
Now there are a hell of a lot more and bigger ships there than Destroyers.
