Corey Hinderstein @coreyah.bsky.social · 03/11/2025The only country to do underground nuclear tests in recent years is North Korea, last in 2017.

Corey Hinderstein @coreyah.bsky.social · 03/11/2025Trump said that Russia, China, North Korea, Pakistan are all "testing" and went on to say, "You don't necessarily know where they're testing," and "They [test] underground where people don't know exactly what's happening with the test." Here, he is a little right and a lot wrong. 8/11 160
Corey Hinderstein @coreyah.bsky.social · 03/11/2025China is also testing nuclear delivery vehicles. Spoiler alert: so does the US, including a planned Sentinel ICBM flight test in 2026. When Trump said on 60 Minutes, "I'm saying that we're going to test nuclear weapons like other countries do." This would indicate status quo. 7/11 160
Corey Hinderstein @coreyah.bsky.social · 03/11/2025Trump also said, "Other countries are testing. We're the only country that doesn't test" Well, it depends what he means by testing, and this interview did little to clear up the confusion.

Corey Hinderstein @coreyah.bsky.social · 03/11/2025One answer to the question, "So why do we need to test our nuclear weapons?" was "Well, because you have to see how they work."

Corey Hinderstein @coreyah.bsky.social · 24/06/2025My point is that these are investments that are supposed to protect us on bad day, when things are unstable, and when we need tools and processes urgently.
