The CIA's Underwater Assassination Period

In 1963, the CIA entered what I'm calling its underwater assassination period. So this was when the agency tried to create an exploding seashell. None of the shells that might conceivably be found in the Caribbean area was both spectacular enough to attract Castro's attention and large enough to hold the needed volume of explosives. They can't find a seashell sexy enough for Castro. And then you're obviously going to go, why am I not running the CIA? You should be running the kill shop. I should.
