Why Do North Koreans Hate Us? One Reason — They Remember the Korean War.
ow many Americans, for example, are aware of the fact that U.S. planes dropped on the Korean peninsula more bombs — 635,000 tons — and napalm — 32,557 tons — than during the entire Pacific campaign against the Japanese during World War II?

This Is What a Modern-Day Witch Hunt Looks Like
All in all, it’s remarkable how many basic facts this letter gets wrong about Tuvel’s paper. Either the authors simply lied about the article’s contents, or they didn’t read it at all. Every single one of the hundreds of signatories on the open letter now has their name on a document that severely (and arguably maliciously) mischaracterizes the work of one of their colleagues. This is not the sort of thing that usually happens in academia — it’s a really strange, disturbing instance of mass groupthink, perhaps fueled by the dynamics of online shaming and piling-on.
