President Trump just started a dangerous, pointless war against Iran The war is not the result of deliberations or consultation. It is the impulsive decision of one man—like dictators do.

@joecirin.bsky.social list of criticisms is long. A few points:

"Iran does not pose an imminent threat."

"Active negotiations showed promise this week."

"No US ally, save Israel, supports this war."

"Innocent civilians in Iran and the region will die needlessly." @thebulletin.org

Trump’s war on Iran: grave dangers and, at best, limited benefits As with the 2003 Iraq war, the path to conflict with Iran has been paved with false statements. Pandora’s box is now open: The consequences of the US and Israeli attack on Iran will be lasting but are...

Iran's nuclear program, "obliterated" last summer, probably hasn't been advanced by much. Regime change by air has a record unbroken by "success." Matthew Bunn writes about these and other reasons to doubt the rationales for and likely efficacy of Trump's new war on Iran. @thebulletin.org

Anthropic’s showdown with the US Department of War may literally mean life or death—for all of us Why the showdown between Anthropic, a major developer of artificial intelligence models, and the US Department of War lead to existential-level catastrophe.

New far more capable AI systems for the life sciences are coming online. These "agentic" systems could carry more risks than already exist with AI. Sarah R. Carter writes "it will be critical to build biosecurity measures into these systems from the beginning." @thebulletin.org

Assad loyalists are regrouping.

Russian opposition leader Alexei Navalny was poisoned with a toxin naturally found on the skin of South American frogs.

His assassination was yet another violation of the international ban on chemical weapons, writes Gemma Bowsher.

And today, German Chancellor Merz said in the opening of the conference that he is talking with French President Macron about European nuclear deterrence.

Why Iran–US negotiations must move beyond a single-issue approach to the nuclear problem If the negotiations scheduled for Friday between Iran and the United States are to be effective and durable, they must move beyond a single-issue on nuclear weapons and toward a comprehensive, direct,...

The experts comment: New START expires, bringing both risks and opportunities Experts share their concern about the no-rules, no-inspections period that opens when New START expires on Thursday. They also see an opportunity to adapt arms control to a multipolar world.

"If it expires, it expires. We’ll do a better agreement," Trump said of the last nuclear arms agreement between the US and Russia. Experts are a bit less blasé about the demise of New START. @thebulletin.org

Iran’s internet shutdown tells a larger story: Digital repression is on the rise Like Iran, governments worldwide rely on internet shutdowns to suppress populations, rig elections and collectively punish their citizens.

Iran, in its 14th day of a digital blackout, isn't the only country to use this tactic to control its citizens. In 2025, an estimated 212 shutdowns occurred across 28 countries, affecting 798.12 million people, write @stevenfeldstein.bsky.social & Shreya Joshi for @thebulletin.org

In a new @thebulletin.org video, @jennifernuzzo.bsky.social and other experts warn that cuts to vaccines, research, and global health initiatives could leave the US far less prepared for the next pandemic.

Trump administration sends letter wiping out addiction, mental health grants The Trump administration sent hundreds of letters Tuesday terminating federal grants supporting mental health and drug addiction services.

This is monstrous: cutting $2 billion from mental health services

RFK Jr has himself experienced a mental health condition

He is certainly aware of the suffering, distress, & mortality that mental health conditions can cause

How is this "Making America Healthy Again"?

Pulling out of 66 international organizations, Trump turns his back on science, facts, reason Under the Trump Administration, international law, conserving nature, protecting children from war, developing renewable energy, and building peace are issues antithetical to US interests.

"What is truly contrary to the interests of the United States is the willful ignorance of the Trump administration on issues like climate change & vaccine safety. Such ignorance is also contrary to the interests of all global citizens who seek to live and thrive on this pale blue dot in the cosmos."

@progmil.bsky.social has the best analysis I've seen so far on the parallels between Trump's declaration that fentanyl is a chemical weapon and Bush's claim that Iraq had WMD, and why that does not bode well for US policy towards Venezuela.

FIFA had it right. Not only has Trump stopped 8 wars, but soon he'll get on the phone to stop one he'd already stopped just a few months ago. If you're keeping score, that's 100 percent more peace in Southeast Asia.

Use all the tools of the trade: Building a foundation for the next era of biosecurity The coming era of biosecurity will demand a broader and more adaptive approach as AI, powerful biological engineering techniques, and globalized scientific research drive progress in biotechnology.

Some great stuff in the @thebulletin.org's 80th anniversary issue. @stephbatalis.bsky.social and @vikramvenkatram.bsky.social, for starters, write about the future of biosecurity governance.
