Early candidates running for the pacifist party, I guess, given I can't recall reading about anyone platforming against existence of intelligence gathering agency. Anyone who could or was running for office that believed America should be only major power post-Ww2 that didn't have spies. Enough votes that direction might have resulted in the dissolution of our intelligence agencies that were forming. And probably the dissolution of or great damage to our country later given the leaders would be acting blind. But you'd have a chance.
"Of course, it's easy to make up a world where it would sort of kind of make sense. That's not the one we're talking about, though."
We are talking about that kind of world. Are you saying there's no allies spying on us with potential economic/political results? Or that there's nobody that might threaten us? Both are ludicrous but such issues are at root of my claim that we need a spy agency. So, which do you reject?
