You've entirely misinterpreted my point, AC. I didn't say there are threats. I didn't say there aren't threats.
My point has nothing to do with whether or not the defense is needed but rather that the defense exists and other first world nations make use of it. If there are no substantial threats, as you imply, then the US using threat intel as a bargaining chip is worthless. However, since other nations value US threat intel, they must see value in it regardless of whether or not the value is real or perceived.
