The gist of the story is that U.S. intelligence agencies admit to going public with unsubstantiated assertions when doing so might confer an advantage to U.S. interests.
It is not that officials lie to the public. Instead, they say things they can’t prove in order to strike a blow in information warfare.
I’m not entirely opposed to policies that allow for the declassification of intelligence guesswork — even weaponizing it — but I think the public needs to factor this revelation into its thinking. To the extent we might distrust something an enemy says, we should also distrust what our own leaders say. It is only prudent.
