As my colleague @gkucs.bsky.social pointed out, "As the Pentagon watches 50 years of investments in forward deployed bases in the Middle East get destroyed in a few months by cheap Iranian drones, Air Force Secretary Troy Meink proudly announces the Pentagon is prepared to win a war in outer space."
