It is often asked what an actual foreign agent would do differently if he were trying to destroy the country.
I don't think that's entirely valid. Nonetheless, there is enough overlap that the question keeps getting raised.
So... perhaps that's what you're missing?
Hanlon's razor still applies: "never attribute to malice that which is adequately explained by stupidity" [0]. He might be such a foreign agents, however we know that he is unintelligent and narcissistic, therefore everyone who makes him look stupid/bad is suddenly "public enemy number one."
Notes:
It's easy to pin this all on a foreign enemy, but this "theory" is completely invalidated by noticing that Trump receives support from all the most powerful person of the country: Musk, Zuckerberg, Thiel, Ellison, Bezos... America doesn't need foreign adversaries to destroy itself.
Or, as the Canadian press wonders, right now, today and continuously, how can we tell if he’s lost his mind?
