Presumably none of the groundbreaking / fun research is carried out at Area 51 anymore.
If you were a research scientist doing classified research, and invented anti-gravity, would the powers behind the scenes allow this technology into circulation? Our guys certainly wouldn't want to let the Soviets know anti-grav is a possibility.
All the U.S. military-industrial complex's best toys are certainly still classified.
If they’ve invented a doomsday device, however, letting the Soviets know should be a top priority for it to function as a deterrent (per Dr. Strangelove’s logic).
