(Reuters) – In North Korea’s effort to become a nuclear power capable of striking the United States, leader Kim Jong Un has telegraphed what his scientists and weapons experts are achieving. Over the past two years, the country has moved from a fledgling nuclear program to possessing the technology to at least strike the U.S. Pacific territory of Guam.
Most Western experts accept that North Korea is close to putting a nuclear warhead on an intercontinental ballistic missile (ICBM) that can reach the continental United States, but this has not been independently verified.
