Dolphin wars in the Black Sea? - In recent years, U.S. Navy dolphins have been deployed to Iraq and Bahrain to patrol for enemy divers

The United States Navy has deployed military-trained dolphins to protect one of its warships in the Black Sea amid rising tensions with Russia over Ukraine, the Russian daily Izvestia reported.

A Russian fighter jet made multiple close-range passes near the USS Donald Cook, a Navy destroyer, on April 12, two days after it entered the Black Sea, passing the Turkish straits. As the crisis in Ukraine deepened, U.S. ship commanders considered the Russian action provocative and inconsistent with international agreements, prompting the ship to issue several radio queries and warnings.
