First of all, thanks for the welcome
I’d agree the significance of Northwoods is overplayed by some, but I think you may be giving it short shrift. Sure, there may be some contingency plan for invading Canada in the bowels of the DoD, but I don’t think such a plan was ever submitted directly to the president by the Joint Chiefs for him to formally approve or reject putting into immediate motion. And yes, it was never used- because Kennedy rejected it. What if Nixon was in there instead? We already know he wasn’t shy about using nefarious means to reach his ends.
I’d also agree wholeheartedly that it’s “used to justify every nut's ideas on any given topic,” and as I wrote in the post, that’s exactly why I’d like to see it given a more nuanced and historical take on it, rather than just “here’s justification for my pet conspiracy theory.”
And yes, there are plenty of other historical conspiracies, which is exactly why I think it could make a good show. Certainly Northwoods itself would be pretty thin material to sustain a show, but it’s always in blending recent and ancient history that makes good HH episodes… bubonic nukes and barbarian biker gangs and whatnot. I’d like to see it omit “conspiracies” that were aimed at some external nation or force (e.g. Pearl Harbor, the Manhattan Project) and focus just on ones against ostensibly “friendly” targets, either to attack internal enemies or as pretext to attack external enemies.
