The Japanese run two separate atomic projects just because the Army and Navy refused to share data. That's pretty stupid.

Stripping down a Zero to ram a B-29 is also pretty stupid. Making a complete assortment of machine guns that need oiling is also stupid, just like creating a Japanese semi-auto pistol.

Most stupid: Balloon Bomb. Then V2, right alongside the sticky bomb. I mean, at least the sticky bomb worked...
