It’s “liberation day” . . . again? But does anybody really know which nations are subject to which tariff rates? Import policy by tweets . . .

Lesotho is nowhere near Botswana it is completely surrounded by South Africa financially it will probably raise a few dollars in revenue.
What is desired is that American folks stop buying all those imported clothes, perfumes, foods, and cars he wants you to buy clothes, perfumes foods and cars made in America like all those big Mustang GT, Dodge, Firebirds with the big thirsty engines under the hood.
As for Zambia and Zimbabwe I don't think there is any significant trade between them and the US most of their trade is with China and/Russia.
In fact most of Africa is veering towards being much more reliant on trade with China and Russia than any one else including the US.
The tariffs are a very poorly thought out strategy that will in its main cause prices to rise in America rather than address trade deficits.
The cause of which is when your own industries inefficient, not competitive and produce products that the people in that country don't want to buy because they cannot see value for money in those products. It was also to a large extent driven by bad decision making in the past where governments decided to clean up the environment (which does need to be done period even more so now), but the strategy was going back not to invest and find cleaner ways of doing it, it was let's simply relocate the dirt elsewhere and put all the dirty factories etc in to name one place China. So basically it was here have all the factories and manufacturing on a plate, we don't want it here anymore. Now oh shit we have a trade deficit??? that is getting bigger and bigger.
Let's correct that with tariffs and penalize the people in our own country by making everything much more expensive, so they can buy the products we get around to manufacturing once we have got around to building the factories and training the work force to make the products.
But prior to that let's use tariffs to piss off every one of our trading partners we have trade agreements with who of course will reciprocate with tariffs on the products we do produce still and at he same time less for good measure let's piss off the rest of the world and put tariffs on the raw materials etc we need to produce the goods because we also ran those industries etc into the ground and we also don't have the work force anymore to do it???
At best those countries elsewhere reciprocate with tariffs or they see you as a non viable and unreliable trading partner and simply adopt we go and find more reliable and viable trading partner policy and say we no longer wish to trade with you, the China, India and Russia etc are much better options.
PS
Oh and those loans that used to get well they are no longer available either so find your own money to cover your shortfalls.

We have dumped the dollar as the trade mechanism. So you won't be getting those fees you collect for the facility of using the dollar anymore.

There is already a push to do precisely this. However we see that you are willing to assist the need to speed up the process.

they're either reciprocal (they charge us X amount, so we charge them the same) and/or due to trade deficits (what we import/export to them vs what they import/export from us); and in some cases, they're a penalty for screwing us over (like countries with questionable ethical practices and those who've outright threatened us)

The days of the US being the world's welfare office are over. If our so called allies want to be friendly, then they can act like it and trade with us on equal terms, otherwise they can pound sand...

Its all blatant market manipulation to extract as much profit from fluctuating markets. Every time the mind attled president makes a tweet people react. The market sinks or rises and people buy or sell to make untold profits. Is the u.s. making progress paying its bills? Idk but unless it is and if it is this all constitutes insider trading by high excellency DJT.
Illegal; but rich old white men can do anything they want and pay lower taxes while the rest of us will forever foot the bill.
