This is satellite imagery of a practice area for military parades in Pyongyang, North Korea. The show of force from the country’s dictatorship is nothing new. But this particular parade happens to come just one day before the Olympic opening ceremonies in neighboring South Korea. North Korea knows it’s being watched. So whatever we’re seeing is what the country is O.K. with showing. The official parade ground is actually here, in the city center. There’s a large permanent viewing stand for the country’s leadership. This is what past parades at this location have looked like from the ground. The nearby practice area is actually a replica of the official site, and even has a viewing stand. Here we see troop formations, what appears to be a military band and columns of military vehicles. Joseph Bermudez, an analyst writing for Johns Hopkins’s 38 North website, thinks there might actually be 13,000 troops practicing in these images. What we don’t see are the latest missile launchers. Analysts suspect they might actually be stored here, in this nearby camouflaged facility. These ground marks may be tracks created by heavy military vehicles kept in these shelters. Some parade activities are practiced back in the city center. This shot shows an image of an empty square. Here is the same square the day after, with scores of people holding red pompoms that spell out a slogan saying, “One against 100.” It’s a message to its citizens, but also to those watching from above, that North Korea sees itself as a nation constantly under threat from the outside world.
