My somewhat more optimistic take on the @UN #NPT Review Conference is out at World Politics Review @wpr.bsky.social. www.worldpoliticsreview.com/non-prolifer...

It was a great honor to meet Tyler Prize laureate Toby Kiers at her award gala recently. Here, I write about Kiers' fungi research & advocacy - and how symbioses between social & natural sciences can spur global governance for hidden issues. www.worldpoliticsreview.com/kiers-tyler-...

Toby Kiers' keynote speech at the Tyler Prize award ceremony is incredible - a light-show of her network data on myochorizal fungi. What an inspiring scientist and issue entrepreneur. Am writing today about her vision for global governance of the underground. www.youtube.com/watch?v=d3o3...

Trump's latest tweet which appears to call not just for war crimes but for all out genocide against the entire Iranian people. Anyone in a position to participate in such crimes should refuse. Here's why and how. Please share widely. www.worldpoliticsreview.com/trump-us-ira...

Iran’s use of cluster munitions against Israel looks like evidence of international law’s irrelevance. But as WPR columnist @charlicarpenter.bsky.social writes, a closer look suggests the opposite may be true.

This Doha Debates roundtable, in which I participated, was recorded last November - still relevant? Give it a listen and tell me what you think. www.youtube.com/watch?v=tXSq...

At World Politics Review (@wpr.bsky.social) this week, I explain more about how we can know that norms against nuclear non-use are getting stronger rather than weaker in an era of nuclear brinksmanship www.worldpoliticsreview.com/nuclear-weap...

In my latest @foreignpolicy.com piece, I trace how the nuclear taboo is increasingly grounded in international humanitarian law rather than the non-proliferation regime. foreignpolicy.com/2025/08/20/n...

More positive news from @umassamherst.bsky.social Human Security Lab: www.militarytimes.com/opinion/comm...

One of the most powerful drivers in Israel's shift on food aid is the Israeli military pressuring Netanyahu to stop forcing them to carry out manifestly unlawful orders. International law at work. www.worldpoliticsreview.com/israel-aid-g...

Military-trained Americans want much stronger nuclear safeguards, worry about unilateral Presidential launch authority, says new UMass Human Security Lab / You Gov poll in Bulletin of the Atomic Scientists thebulletin.org/2025/07/mili...

My latest column on why Trump should double down on, not pull out of, UN peacekeeping: www.worldpoliticsreview.com/un-peacekeep...

The nature of the US-El Salvador deportation scheme means that Trump could be indicted by the International Criminal Court. @charlicarpenter.bsky.social explains how it could happen:

One does not simply break the rules-based international order. On the American Prestige podcast this week, I talk with Danny Bessner and Derek Davison about why. Subscribe to this excellent podcast and listen here. (Non-paywalled version available in comments.) open.spotify.com/episode/7w6K...

As I head with students to the UN's nuclear ban treaty conference next week, I'm excited at my lab's emerging research findings: this treaty's very existence can and does change minds about the lawfulness of nuclear use. @nuclearban.bsky.social

My brother Lt. Col @ehcarpenter.bsky.social's new book about his time as a peacekeeper in South Sudan is topping the charts at Amazon! A great resource for classrooms, scholars and the general public interested in world affairs… and he's about to start a book tour as well: bit.ly/3QmwT9H

Guys! Here is a great new website where you can find lots of ways to get involved in protecting our human rights and fundamental freedoms. Filter by location, issue and type of event and find ways to keep the pressure on Trump to follow the constitution. Happy Monday! www.buildtheresistance.org

an early sign that institutions will hold after all? www.nytimes.com/live/2025/01...

Whew.

Civilian protection may sound like a bleeding heart issue, but the military gets tons of strategic benefits for its civilian harm mitigation dollar. Here’s why the DOD’s Center for Civilian Protrction is a bad candidate for Trump’s chopping block: www.worldpoliticsreview.com/us-military-...

my latest column in World Politics Review @wpr.bsky.social: the death of the Rules-Based Order is being somewhat exaggerated

@hsecuritylab.bsky.social's new report says Zelensky should lift the ban when martial law renews in August; @StateDept & @NATO should encourage this. Why? For humanitarian and strategic reasons. To find out more, read this THREAD (if you're still on Twitter):

Over 500 days into the Ukraine war, Zelensky's travel ban on civilian men is not just hard on civilians, but unnecessary and counter-productive. New report out from @hsecuritylab.bsky.social

New @HSecurityLab survey shows majority of Ukrainians continue to oppose @ZelenskyyUa's travel ban on men 18-60. Only 42% are in favor of retaining the ban, 58% split between "Let Men Choose" or a "Different View." http://bit.ly/44uw4AM

Russia is the predator AND it's important human rights groups look both ways. @hrw.org doing that now on cluster munitions. Perhaps next on (say) the gender-biased ban on civilian men crossing the border... ??https://www.worldpoliticsreview.com/zelensky-ukraine-human-rights-putin-russia-war/

ok, yes i too am now one foot in Twitterhell, one in the Twitter exodus. for my inaugural BSky post I'll re-up an early LG&M essay from a whopping thirteen years back... funny how it still fits the current zeitgeist
