U.S. Looks to Build Missile Shields

Madelyn Creedon, an assistant secretary of defense for global strategic affairs, said Monday that the U.S. might try to build regional missile defense shields in Asia and Middle East, a move that could strain relations with Russia and China. Pentagon officials say the new infrastructure—which would be built in conjunction with Japan, Australia, Japan and South Korea—would defend against attacks from Iran and North Korea. Because the demand for more missile shield technology will grow in the coming decade, the U.S. is looking to develop and deploy mobile capabilities.
