What exactly is the government hiding in Tucson? Not much, says @nuclear-jim.bsky.social. He got an interesting souvenir there, regardless.

I feel pretty strongly the @nytimes.com has the wrong framing here. This isn't serious; it's pathetic.

I'd suggest something like:

"Trump throws social media hissy fit invoking nukes after public spat with ex-president of Russia."

As much as I deplore nuclear signaling by tweet--can't believe I just wrote that--I would NOT necessarily assume there's a been change to the US nuclear posture. The U.S. always keeps ~4/5 SSBNs at sea ready to fire.
