This isn't a good thread to discuss Q, and the Q threads provide the context that may answer this question.
That said, I think the "too deep" is a reference to hidden personal and political relationships that transcend borders, e.g., US and parts of the Nazi war machine were cooperative before during and after WWII, with family effects that persist to this day. My take is that history is more complex than most of us are given, and the "deep truth" that world governments are substantially puppets of larger forces is in fact reality.
I also think there is little or no value in plumbing history. Doing so distracts from the mission. Secure the borders, and try to restore the American dream.
Nice post and guidance.
We are seeing history being made in the form of The Donald returning Washington to the people.
If you haven’t seen it watch Darkest Hour about Winston Churchill.
Great movie Re leadership that can change history and the British version of deep state...
Well worth the time spent
