North Korea's Kim has recently threatened to "settle accounts" with the U.S. and posed near a chart that appeared to detail bombings of American cities w/Washington DC one of four targets.
North Korea Eclipses Iran as Nuclear-Arms Threat Pyongyang, as a result of decades of covert atomic work, has already or is close to mastering the technology to mount one of its estimated dozen nuclear warheads atop medium & long range missiles that are capable of striking U.S. allies South Korea and Japan as well as the USA! By many estimates, North Korea will have the ability to deliver nuclear weapons using long-range ballistic missiles to distant targets within four to five years. Estimates range from 40 to over 100 long range nuclear missiles.
North Korea may furnish terrorist w/nuclear weapons as well. And let's not forget Iran, may have a nuclear bomb sometime this summer.
IMHO, If you live in Washington DC you may want to move while you still can.
