Will this finally persuade Trump that Putin is not on his side? Will Ukraine’s offer of anti-drone technology persuade him that Ukraine is?

Facts and physics still matter: a response to Wilson’s historiography Harvard University historian Benjamin Wilson's piece in the Bulletin on Hans Bethe and Richard Garwin fails not because his historiography is provocative, but because his understanding of…

The legacies of physicists Hans Bethe and Richard Garwin are "important to issues of nuclear war and peace, to history, and to the Bulletin readership," writes Herbert Lin, a senior research scholar and research fellow at Stanford University.

Last night, I left the classified briefing on Trump's war in Iran and heard nothing about a plan to meaningfully address Iran's nuclear capabilities.

Iran's stockpile of highly enriched uranium should be the administration's primary focus. That is clearly not the case.

47 years and still waiting. I suppose that's imminent on a cosmological timescale. Maybe even a geological timescale.

Laura Rozen’s report on the briefing by US officials on negotiations over Iran’s nuclear program reveal how thoroughly out of their depth they were. And they provide no evidence of an imminent threat from Iran. open.substack.com/pub/diplomat...

Our strength lies not only in our military capabilities, but in our democratic values enshrined in the constitution and in the institutions that uphold them. Neither must become collateral damage.

Illegal U.S.-Israel Attacks Not Justifiable on Nonproliferation Grounds | Arms Control Association

Whatever else you might think about Iran, you should know that its nuclear program posed no imminent threat. The false claim of such a threat is not the reason for this attack but a pretext. www.armscontrol.org/pressroom/20...

My hunch is they’re planning to use unspent USAID funds from FY 2025. I think most USAID appropriations are 2-year funds, but they may already be obligated for other purposes. I haven’t heard anyone mention this possibility, so maybe it’s not a real option.

The Trump Administration insists that Iran must stop enriching uranium. Iran insists on its right to enrich. But there's a deal to be made if both sides want it. My latest in the Bulletin of the Atomic Scientists. thebulletin.org/2026/02/give...

Four years have passed since Russia's full scale invasion of Ukraine. Russia was supposed to win in three days. Instead, Ukraine reinvented modern warfare, built a drone industry, and can destroy a thousand Russian soldiers in a day. Ukraine can win.

In addition to being wrong on the law and wrong on the science, as Holden says, the repeal of the endangerment finding is also wrong on the economics. The finding is needed to correct the market failure that allows polluters to impose the costs of pollution on others.

The reckless repeal of the Endangerment Finding The repeal of the Endangerment Finding is scientifically unfounded, almost certainly illegal, and unbelievably unwise.

The Washington Post opinion pages have become economically and technologically illiterate. Recent weeks also saw a nonsense editorial and op-ed embracing the repeal of the climate endangerment finding.

What’s most worrisome about this is that Witkoff & company may be so out of their depth that they believe this alarmist nonsense. And that could tip the balance toward a military strike.

Intriguing 2-part claim: 1️⃣ multi-year funding for DOD operations in the Boondoggle Bill violate violate the Constitution's two-year appropriations limit for "Armies" and 2️⃣ the same prohibition applies to federal law enforcement (ICE and CBP) which act as "Armies" under the intent of that clause.

Kash Patel is weaponizing the FBI against political opponents. NSPM-7 is based on the lie that Antifa is a domestic terrorist organization and that dissent from the Trump regime's policies is support for Antifa.
