Only a “useful idiot”, unaware that they are serving foreign interests, would act in their own country in accordance with a sabotage manual describing how to attack a world-war adversary.
If I’m living under a fascist government, I’m gladly serving foreign interests because those will be my allies in bringing it down.
Unless their own country is run by fascists and implement draconian policy.
… and serving foreign interests.
What if the foreign interests align more with the citizens’ than domestic interests?
no, that calls for a much more constructive approach than just “breaking things” or “gumming up the works”
No it doesn’t.
Nobody in the Third Reich believed a “much more constructive approach” was the answer. The only solution to the Third Reich was breaking the Third Reich, and the same will hold true of the American Reich soon.
You’re gumming up the works right now.
