I'm convinced this was a psy-op from the beginning. Notice how it's nothing more than a proposal, which costs basically nothing. Yet for years through popular culture osmosis I've heard people confidentially say everything from it was researched all the way to saying there 100% is a working "gay bomb". It's almost like the word of it was intentionally spread and prodded to amplify.
The US military doesn't need to actually research a "gay bomb", they just need to make it public knowledge that they are "researching" one. When opponents are conscripts in Iraq and various Balkan groups, who are among those cultures who really don't want to be seen as gay- then the threat of a gay bomb is as effective as a real one, and for a fraction the cost.
