I think some context would be helpful to parse the specific things he's referencing, but, here's my partial translation/paraphrase:

"I'm smart. My uncle was smart too. I went to Wharton, he went to MIT. He was a nuclear scientist. You know, I feel like people don't give he and I the credit we deserve. We have good credentials but people don't pay attention to that. They think I'm stupid because I'm Republican. But if I ran as a Democrat, they'd think I'm smart.

Anyway, my smart uncle told me that nuclear energy is really powerful and efficient. And that was 35 years ago, so I imagine it is even more powerful and efficient now.

Now I'm going to tell you about three or four prisoners. Some are male and some are female, I think. The female ones are smarter.

But anyway, the Persians/Iranians are great negotiators. The US should have negotiated harder with the Iranians. But I feel the Iranians ended up getting a good deal regarding our nuclear negotiations. And I feel that the United States' economic and security interests have been harmed by the deal we made with the Iranians, who are smart."

I'm angry at myself for wasting my time reading that garbage.

What was he trying to accomplish with that speech? Educate a classroom of college students? That's what lecturers are for. What was he trying to accomplish? He was trying to win a political race. He succeeded. It's annoying when people act like Trump is an idiot. (Or GWB before him. It was EXACTLY the same pattern.) Hate him a little or hate him a lot, he wouldn't have become president if he were an idiot. One could strongly argue part of his success is due to people underestimating him so much.

You just have to parse it as a tree

Sounds like someone with a thought disorder.
