Despite growing concerns about a nuclear strike on the U.S. by North Korea, emergency management officials in Washington state say they are prevented from forming an evacuation plan in the event of a nuclear attack. An effort is underway to change that. Multiple reports on Tuesday indicated U.S. intelligence believed North Korea had reached the capability of miniaturizing a nuclear warhead to make it small enough to load onto a missile. That development comes years earlier than previously thought. President Donald Trump responded with a warning. “North Korea had best not make any more threats to the United States,” Trump said Tuesday. “They will be met with fire and fury like the world has never seen.”
