USA did this once. (Score 2, Interesting)

The USA did this to Bayer in the early 20th century (WWI?) with aspirin. IIRC, Bayer held German and US patents on the drug. The US gummint decided that the drug was vital to national security and directed other folks to manufacture it. Bayer was never compensated for its loss, and came close to closing. Bayer never regained US market share, either.
