WASHINGTON — On Saturday, President Donald Trump held a hideously expensive military parade in Washington, D.C., on his birthday. Trump and his top officials stood on a stage at the National Mall behind two tanks, before two large digital American flags. Military bands and troops, some on horses, some in vehicles, some in tanks, others in Howitzers, marched in the streets. So did a few robot dogs. An army parachute team jumped down. Helicopters flew over. Drones flew by. There were many, many tanks.

The spectacle was billed as honoring the U.S. Army’s 250th birthday — and planners put in admirable effort to sell this fiction, with processions designed to honor key times in American military history. In reality, the event was just one part of the Trump administration’s vast, billion-dollar government effort to make the leader feel good about himself.
