They had actual funding then. And people actually listened to them. There's a good reason nobody in the intelligence community listens to the CIA anymore. They're tosh.
It seems a common affliction of people who don't live here to realize that this is, well, a big place. The CIA could, back in the fifties, cause what amounts to annoyance in a country that is about the size of, say, Washington state. It would cost infinitely more now, and you can't stop at one state if you seriously hope to alter the outcome of the next election. The smallest state in the US, Rhode Island, is about a hundred fifty square miles or so. If you want to seriously stop the Democrats winning the next election your best option is to knock out New England, and frankly that may not be enough, so California too. These two areas are seperated by 3000 miles and lots of areas that could vote Republican that you don't want to put under martial law. So, it's now two seperate emergencies. Maybe more, since New England is about the size of, say, the British Isles and about as densely populated. This is no mean feat. I don't think you could have a real emergency short of armed invasion or civil war that would cover even one of the two you would need.
What are you going to do? Claim Canada's invading Maine?
