I don't know if Trump's tariffs are "righteous" but I think that is an unfair question. The first question I would like to know is was the path we took to strip the US of its manufacturing righteous? Because if not, then it is not righteous to defend something that is unrighteous and it is perfectly acceptable to tear it down.
I also don't know if the Tariffs are the best way to remedy the situation. I think what is clear is that no president since NAFTA has remedied the situation, and to be fair this began after WW2. First we rebuilt Eastern Europe and much of the world, then we brought in NAFTA to strip the US manufacturing. So instead I think the more appropriate question is whether or not Trump is addressing the issue that he promised he would address, a promise that motivated many to vote for him. Yes, he is addressing it and yes, he is doing what he said he would do. This is what the majority of Americans wanted and that is how our form of government works.
Are people losing their jobs? Yes. Is this because of Trump? That is not a simple question, I would say it is because of the $36 trillion debt. However, it could also serve his political interests, that is certainly possible. This is what happens when you borrow money, you have to pay it back and people rarely like the terms under which they must pay off their debts.
The one think I think should encourage people is that Trump has two sons and a daughter that might have political ambitions, so he can't simply say this is his last term and he doesn't have to worry about the future. If we are going to have 24 more years of Trumps in office after Donald then it is on him to fix this problem.
