LONGMONT, Colo.—In an anonymous office building in the shadow of the Rocky Mountains, in a part of Colorado where cattle ranches fade into strip malls, a gravel-voiced man with a Brooklyn accent is virtually moving through the streets of Pyongyang.
Joe Bermudez is staring at a computer screen of a detailed satellite image, maneuvering his cursor past guarded checkpoints and into restricted neighborhoods where the North Korean elite live behind high concrete walls. Looking down on the city from more than 250 miles up, he lingers over what he believes is the private airport of Kim Jong Un, North Korea’s young leader, pointing out a pair of VIP helicopters and a Soviet-era biplane. He moves north, jumping across the countryside and picking out hidden tunnels, walled compounds, and a small flotilla of military hovercraft designed to storm South Korea’s beaches.
