Regarding Japan, Trump claimed they would invest $550 billion in America, so tariffs were lowered to 15%. 

But Japan now says it's not an investment, but a loan of over $500 billion at the market interest rate of 4%.

The deal with Korea was similar—Trump announced he had secured a $350 billion investment fund from Korea. But the Korean government says it would be a loan to America, not for investment purposes.

Then Trump made a deal with the EU— $750 billion for energy purchases and a $600 billion investment promise in America, specifically as Trump wanted. 

In exchange, the EU secured a 15% tariff rate.

But the deal turned out to be a total humiliation for the EU. 
Von der Leyen (Top EU Diplomat) was heavily pressured, and now she says she probably can't manage the $600 billion investment fund for America. 

Trump threatened that if the funds don't come, tariffs on the EU will go up to a flat 35%.

On top of that, the INDIA issue came up. 
Initially, Trump set a 25% tariff on Indian goods. 

But because of India's purchase of Russian oil, he added another 25%, making it a total of 50%.

This means American consumers will pay more to buy Indian goods because of Ukraine—so where is "America First"?

Just hours ago, Trump said he would impose a 100% tariff on chips and semiconductors entering the U.S. (except from American companies). Yesterday, he announced tariffs on pharmaceutical products could soar to 200%. In summary, tariffs have failed to bring industries back to the U.S.—which was their main purpose. And now, deals with foreign nations have turned into a complete mess.
