I've said this several times here and nobody believes me. If you think it's a good idea to reduce the trade deficit, the way to do it is with lower government spending and higher private savings, not tariffs.
The link below is to an article in Forbes written by Steve Hanke. Hanke is no clueless nimrod. He was an economic adviser to President Reagan. He's a professor at Johns Hopkins, director at the Cato Institute, and, most importantly, the "go to guy" for many countries that had currency crises:

Basically, he repeats an identity, that the trade deficit must equal (private savings - private investment) + (government revenues - government expenditures). And he shows recent government data to back up the identity. He's simplifying things a bit, by not considering trade in services and dividend and interest income. However, if he included that, it should make his case all the more compelling.
He concludes,
As it turns out, the Trump administration’s fiscal policies, which promise an ever-widening fiscal deficit, will throw a spanner in Trump’s trade policy works. If his fiscal deficits are not offset by an increase in private savings relative to private investment, increases in the Federal deficit will translate into larger trade deficits. So, the U.S. trade deficit will not only be made in the good, old U.S.A, it will be made by President Trump himself, an arch-enemy of trade deficits.
