Start at part 1, stick with it. Unlike a lot of others here, I like giving "easy answers" when respectfully requested - I get not everyone has the time.

This particular set of knowledge has no easy answers. It's too brilliant to distill. The fact it's so confusing is also hugely relevant to why it is also an effective strategy by the Trump team.

Do yourself a favor and muddle through it a couple of times. Read in full the scans Patel provides. Take your time. FWIW, you're no alone in your position - I've shown this to some big brains I know, and it's confusing to them as well. It's worth the rigor. Extremely worth it.
