Mine tenker om atomvapen i Nettavisen: www.nettavisen.no/norsk-debatt...

A student just referred to me as the one who “loves shrek and hates nazis” and tbh she cooked with that one

BREAKING: IAEA chief Rafael Grossi says there is a “rapid increase” in operations at North Korea’s Yongbyon nuclear reactor, warning of a “very serious increase” in Pyongyang’s capability to produce nuclear weapons, now estimated at a few dozen warheads.

On January 25, 1995, scientists in Norway launched a meteorological research rocket. It was immediately picked up by Russian early warning systems designed for nuclear weapons. The incident is important to reflect on today, write Jamie Withorne @jamiewithorne.bsky.social and Raven Witherspoon. ⬇️

In our latest with @thebulletin.org Raven Witherspoon and I discuss the implications of a historical Norwegian “close call” and Russian escalatory response. We unpack implications for pre-launch notifications today, especially in an era without New START. Link 👉 thebulletin.org/2026/04/what...

The Andoya rocket launch incident is an important reminder of the value of pre-launch notifications, which is especially salient now that New START has expired, Jamie Withorne (@jamiewithorne.bsky.social) and Raven Witherspoon write in @thebulletin.org. #NewSTART #nuclearweapons #nukesky

“How’s the phd going???” Me:

Call it cricket’s revenge

Tja, warum auch: "The United States joined Russia, China, and ‌Niger on Thursday in opposing a resolution adopted by the U.N. nuclear watchdog's board denouncing attacks on Ukraine's energy infrastructure as a threat to nuclear safety, diplomats said."

If someone asks “do you know where the uranium is?” And the answer *isn’t* a resounding yes… that’s a bad sign.

re-upping for no particular reason

h/t to the political scientists who still cannot classify this as war until we reach 1000 battlefield casualties

Norway to "speak" about nuclear weapons with France but will not host any weapons. "Vi skal ikke ha atomvåpen på norsk jord i fredstid, sa utenriksministeren i Stortinget tirsdag formiddag." www.vg.no/nyheter/i/Ex...

We obtained the first publicly released satellite image of Ayatollah Ali Khamenei's compound in Tehran, after it was struck by Israel/US. There are several destroyed buildings. Current whereabouts of Iran's supreme leader are unknown; compound used as his official residence. 🛰️📸: @airbus.com

Abolish ICE. Really.

🚨 JUST IN: If the United States deploys advanced short-range ballistic missile systems to Norway’s Finnmark or Finland’s Lapland regions, and Russia detects them, a crisis similar to the 1962 Cuban missile crisis will ensue, writes Vladimir Marakhonov in @thebulletin.org. #nuclearweapons #nukesky

In this recent blog post I show how publicly available technologies like satellite imagery and SAR can be used to "fact check" aggressive nuclear rhetoric.

☢️ #NuclearPoliticsParadox No.26 💻 Technology isn't a cure-all. But it can help reduce the risk of #NuclearWeapons crises. 🔍 @jamiewithorne.bsky.social shows how increasingly accessible information can harness transparency and 'fact check' the credibility of nuclear threats. 👉 bit.ly/4qEPq29

feels like we gotta start differentiating between nuclear signaling and sheer nuclear ignorance

The president wants to resume nuclear testing. This is a really bad idea - and he can't even get his facts right about why he wants to do it: www.theatlantic.com/ideas/archiv...

What an awesome team to join!

I feel like this photo of masked, armed men pepper spraying a pastor protecting his community is going to be a defining picture of this moment in America for a long, long time.
