🎉 Our 1st @erc.europa.eu #MICROCODE article is out! Using a cross-national survey experiment,
@smetanamichal.bsky.social, @mvranka.bsky.social & @ondrejrosendorf.bsky.social find that formal alliances boost public support for military intervention globally, but the effect is smaller outside NATO.

🔵 Do politicians trade human rights for the benefits of arms deals? Not more than citizens do. Those are findings from @tobiasrisse.bsky.social & @chrisvsteinert.bsky.social's survey experiments conducted on public and elite samples in 🇬🇧 & 🇩🇪. Just published in JCR: doi.org/10.1177/0022...

3/3 Cyber attacks were the most favored, followed by conventional strikes, then cluster munitions. WMDs were the most disfavored overall: chemical weapons were more preferred than biological. Nuclear weapons are least acceptable. @ims.fsv.cuni.cz @fsv.charlesuni.cuni.cz

2/3 They find an overall aversion to civilian casualties & confirm that public support for weapon use is driven by categorical heuristics.

☢️ 1/3 What makes a weapon too horrific to use? Our researcher @laurensukin.bsky.social & her colleagues
David Allison & @herzogsm.bsky.social fielded a survey experiment on a U.S. sample, investigating public support for use of different weapon types. Open access: academic.oup.com/jpr/advance-...

Íránista Jakub Koláček: Po bombardování režimy nepadají, změnu v Íránu musejí udělat lidé zdola Svět s napětím sleduje vojenskou eskalaci mezi USA, Izraelem a Íránem.
