Did the US use biological weapons during the Korean War? The US government says No. Frank Olson apparently thought otherwise.
In Wormwood and Gall, I look at the story: the facts, the accusations, and the cover-up. And I point to indications of another terrible crime, one that might provide the key to the death of Frank Olson.
If the United States deployed biological weapons during the Korean War, it would be the second time China had experienced biological attack within ten years. And that probably would have been no coincidence.
