Two things prove that Trump's tariff war is over:

First, on April 9, it was announced that the collection of certain tariffs would be suspended for 90 days for most countries outside of China.
Secondly, on April 12, it was announced that there would be exemptions from high counterpart tariffs on electronic products such as smartphones/semiconductors.
This fully demonstrates that Trump cannot withstand the pressure from the business world and has given in; it's just a farce.
