Q: Are you exchanging written letters with Kim Jong Un? TRUMP: I can't tell you that. But I get along with him great. He has 57 very powerful nuclear weapons. He's gonna be fine.

Listen I’m not saying we can trust that Trump didn’t just completely make up this number but I am saying that if he just disclosed the classified US estimate then I’m feelin preeeetty proud of our team’s estimate 😌

As an open source analyst that uses satellite imagery pretty much daily, this “tool” is one of the dumbest and most irresponsible things I’ve ever seen. Google just throwing fuel directly on the fire of disinformation and making the verification challenge even worse

1/n - Trump says something about nuclear weapons tests...It’s hard to know what he means. As usual, he’s unclear, all over the map, and wrong. 1. The United States has more Nuclear Weapons than any other country. Wrong. Russia has more nuclear weapons than the United States.

I’ll give someone $1000 if they can find one factually correct statement in this post

View full thread

More than likely, Trump is either just trying to make inflammatory threats, OR he means a very different type/level of nuclear testing than what his post implies and doesn’t know that “start nuclear weapons testing” has a very specific implication (because, well, he’s not smart).

To be more specific, as many others have pointed out, Trump is ~probably~ referring to testing nuclear delivery systems rather than explosive nuclear testing, particularly since that *would* be DOD's responsibility. (and probably in response to Russia's cruise missile test earlier this week)

Me making a social media appearance for the first time in months to make fun of Donald Trump

I’ll give someone $1000 if they can find one factually correct statement in this post

1. The U.S. does not have the most nuclear weapons (Russia does). 2. Truly don’t even know what he could mean by the second sentence. That did not happen. 3. China will not be even with us in 5 years. 4. No other country is conducting nuclear weapons testing. “On an equal basis” = not at all

5. The process could literally not begin immediately. 6. DOD is not even the entity that would conduct nuclear testing - DOE is.

Interestingly, following recent reports that Sentinel would require "predominantly" new silos, the GAO report says only: "the Air Force is reassessing all aspects of its plan to field Sentinel, including the extent to which Sentinel will use the existing Minuteman III launch facilities."

With the new GAO Sentinel report out, this feels like a great time to promote @mattkorda.bsky.social and I's recent report on Sentinel: The Two-Hundred Billion Dollar Boondoggle. We knew the Air Force would have to life-extend MMIII (and that they could have all along). Read more below 👇

GAO confirms what Defense Daily reported back in January: "Air Force officials are assessing options to potentially operate Minuteman III through 2050." I seem to recall many arguments in favor of Sentinel resting on the premise that Minuteman could not be life extended 🤔

80 years since the US dropped a nuclear bomb on Hiroshima. This is not history - there are still survivors of this bombing alive today. It is our duty, as the last generation capable of hearing their direct testimony, to listen to their stories and ensure it never happens again.
