Excited to share a new article in @iojournal.bsky.social with @mchorowitz.bsky.social! We evaluate the risk of states using automated nuclear launch systems to facilitate revisionist coercive efforts. Unfortunately, we find the danger is real and should be taken seriously doi.org/10.1017/S002...

As President Trump withdraws the US from intl agreements - including the Paris Agreement and WHO - Lotem Bassan-Nygate and I ask how this affects public opinion towards cooperation? We descibe our recent findings in @goodauth.bsky.social : tinyurl.com/goodauth @harvardkennedy.bsky.social 1/4

Wondering how domestic polarization is bleeding over into foreign policy? Interested in why Trump is cozying up to right-wing countries like El Salvador + Russia while menacing left-wing Venezuela + Denmark? Check out my updated working paper w/ Dom Tierney preprints.apsanet.org/engage/apsa/...

"The use of history to shed light on current events can be dangerously misleading. The parallels are never exactly parallel." Read the latest from CMIST’s @joshschwartz.bsky.social and Paul Lendway at Stanford, via Pittsburgh Post-Gazette: www.post-gazette.com/opinion/insi...

Historical analogies are omnipresent in foreign policy debates—like accusations that Trump's Russia-Ukraine peace plan is akin to appeasing Hitler. But are analogies an effective rhetorical tool? Check out my new article w/ @chriswblair.bsky.social & Paul Lendway. doi.org/10.1177/0022...

What real-world lessons, if any, can we draw from the recent nuclear film "A House of Dynamite?" CMIST's @joshschwartz.bsky.social cautions that the film’s core dilemma is a false one. Read his analysis, today in Modern War Institute mwi.westpoint.edu/the-false-ch...

Netflix’s House of Dynamite is great drama, but terrible nuclear strategy. Hopefully real-world policymakers are more savvy than the fictional ones in the film. Our survival could depend on it! Check out my take t.co/eQbzUrXUFM

“History shows that staying power — not striking an invader’s homeland — is how the weak beat the strong.” Read the latest from CMIST’s @joshschwartz.bsky.social on why it is possible for Ukraine to win without attacking Russia, today in @post-gazette.com. www.post-gazette.com/opinion/gues...

🚨 It’s publication day! THE ART OF COERCION is finally out. When do threats work? When they are perceived as credibly *conditional*. Credible and painful punishments are not enough. Threats fail if targets feel “damned if they do and damned if they don’t.” shorturl.at/qa4T5

I sat down with @joshschwartz.bsky.social to discuss a bunch of big issues with drones: the frontlines in Ukraine, Russian targeting of Ukrainian cities, Operation Spiderweb, the Israel-Iran War, and U.S. investment decisions on drones. www.youtube.com/watch?v=Femj...

“If the Pentagon does not adjust to the new realities of warfare, it will lose the ability to deter adversaries’ aggression before it occurs—and perhaps the ability to win wars,” warn @mchorowitz.bsky.social‬, @laurenakahn.bsky.social, and @joshschwartz.bsky.social.

What does the Israel-Iran War / Russia-Ukraine War suggest about emerging tech and the future of warfare? Excited to have a new @foreignaffairs.com article w/ @mchorowitz.bsky.social + @laurenakahn.bsky.social on how to bring balance to the (military) force www.foreignaffairs.com/united-state...

So many questions about this attack, but one big one—Where is the highly-enriched uranium Iran had already produced?? Was it destroyed? If not, that seems like a huge problem for preventing Iran from getting a nuke in the short to medium term. There’s also a long-term issue with the attack (1/3)

How are drones transforming modern warfare? On today's episode of CBC's Front Burner, CMIST's @joshschwartz.bsky.social joins Jayme Poisson to explain how drones have become increasingly important to both sides of the Ukraine-Russia war and in conflicts around the world. www.cbc.ca/listen/cbc-p...

How are drones reshaping war in light of Ukraine's successful surprise attack against Russian airbases? I had an opportunity to join the @cbcnews-rss.bsky.social Front Burner podcast (Canada's version of the NYT Daily) to discuss www.cbc.ca/listen/cbc-p...

What explains the dramatic swings in US foreign policy we're seeing? Besides a democratic peace, I argue in a new co-authored @apsa-preprints.bsky.social that there is also a Right-Wing Peace and a Left-Wing Peace. Come for the experiments and stay for the MIDs analysis go.shr.lc/4jucw6O

Does politics stop at the water's edge? Nope! Dom Tierney and I argue in a new @apsa-preprints.bsky.social working paper that domestic left-right divisions over culture war issues like immigration and LGBTQ rights are bleeding over into foreign policy. Read more below

yes this is famously how free societies treat their universities

It's a Mad, Mad, Mad, Mad World responsiblestatecraft.org/trump-tariffs/

Does the madman theory of int'l politics justify Trump's trade war? I'm skeptical because trade wars are two-level games and the madman strategy is often unpopular among domestic audiences. Check out my take in Responsible Statecraft responsiblestatecraft.org/trump-tariffs/

Does investing billions in the F-47—a next generation manned fighter aircraft—still make sense in an era of drone warfare? Probably yes due to its stealth capabilities. Read more in my piece with @mchorowitz.bsky.social in @warontherocks.bsky.social t.co/PNmR1A06vP
