Chairman of the Joint Chiefs of Staff of the United States General Martin Dempsey has claimed that in the case of an escalation of unrest in Crimea, the U.S. Army is ready to back up Ukraine and its allies in Europe with military actions.

According to the Web site of the Atlantic Council, Dempsey said that “he’s been talking to his military counterparts in Russia, but he’s also sending a clear message to Ukraine and members of NATO that the U.S. military will respond militarily if necessary.”
