Bret Stephens: Are we sleepwalking through a ‘decisive decade’?

Last week, the Air Force unveiled its first new strategic bomber in 34 years — a boomerang-shaped stealth plane called the B-21 Raider that may ultimately cost taxpayers some $200 billion — and the country barely noticed. Also last week came reports that China’s nuclear warhead stockpile had doubled since 2020 and could reach 1,500 by the mid-2030s, closer to parity with the United States and Russia. This also went mostly unnoticed. Maybe we were too busy freaking out over Elon Musk’s takeover of Twitter.
