The intro of this article on some of the goofier things the Pentagon has considered as weapons starts out "The US military investigated building a "gay bomb", which would make enemy soldiers "sexually irresistible" to each other, government papers say." But I think it should be pointed out that the US military has always tried lots of weird things. It's how our military works.
I mean, really... spending trillions of dollars on a bomb so powerful it could wreck an entire city? Please. A computer network capable of automatically routing around damaged nodes, knitting together all digital devices? Ridiculous. A bomb that uses satellites whirling in space to find a specific window in a building? Laughable.
All an idea needs is someone to think it up and someone else to fund it, and you can't always tell the good ones from the bad ones just by looking. So what if 90% are loopy one-offs? 7% work and 3% end up changing the world. As long as someone is watching the till, it's OK with me.
Of course, the only one watching the till right now is Congress, which is simply a different way of saying "nobody is watching the till." Hence the first amendment and the related Freedom of Information Act. If nobody else will, we will. It's our country, after all. Mighty clever, those founding fathers.
