The U.S. targeting Iran

The U.S. has sold a $3.5 billion antimissile interception system to the United Arab Emirates. It's part of an growing military build-up directed at Iran. The deal, signed on Dec. 25 and announced on Friday night by the U.S. Defense Department, "is an important step in improving the region's security through a regional missile defense architecture," Pentagon press secretary George Little said in a statement.
