The U.S. Navy has deployed a nuclear-powered submarine to the Middle East.

The move is seen as a warning to Iran that it will not be left alone in the region. The deployment of the submarine is part of a broader effort to deter Iran from attacking the U.N. and its allies. The U.K. and the Arab world are also concerned about the deployment of a nuclear submarine in the Gulf of Mexico, which could be used for attacks on them. The decision to deploy the submarine was made in response to the threat of Iranian attacks.
