Re: Trump doesn't even know the tariff he wants to impose on 56% of the world(BRICS)
I agree with everything here that you said, but do you think Trump "fears" anything? The problem I see with that assumption is that he would have to be able to understand what's going on in the first place. He is resistant to advice, meaning that even if his advisors tell him this is not good, he doesn't care. There were a few incidents now when he was informed that some of his own more important people said the opposite of what he is saying (like the Iran thing), and he simply says: "well, then they are wrong". Lol. Fear assumes understanding of the matter, I fear he doesn't understand.
You are probably right, he is too dumb to feel anything. His understanding of the world is at the level of some dumb holywood movie like Top Gun LOL. But there is still a system in place that makes the decisions and all these tariff wars, other armed conflicts, the isolation of USA, etc. is their doing. And when we look at the overall policies of USA we can see that they haven't really changed with the presidents! For example Biden ran with same tariff war and armed conflicts strategy. The only difference was that he didn't tweet about it 20 times a day 
I have seen people in the USA who failed to say 3 cities from Europe, the educational system failed them, they walk around without any proper knowledge, their top scientists are great of course, and people who go to Harvard and yale and other ivy league schools are great of course, there is no denying that, but 90% of the population says stuff like "capital of France is Italy", so obviously they got a president like trump because of it.
Haha. When a large number of Americans believe chocolate milk comes from brown cows, you know the educational system has failed beyond hope...
