sorry for dumb question but here it goes: I remember during the first administration, Trump launched some tariffs against us and if I recall correctly, it resulted in the signing of the USMCA which replaced NAFTA.

So, where I get lost is, are these agreements non-binding? Like a country can just choose not to follow them and face no consequences before they expire? Cause I'd assume that what the U.S. is doing breaks the conditions of the USMCA?

and if it's non-binding, then that means that even if another agreement is signed yet again, if Trump wants to throw a new tantrum halfway through his presidency and do tariff wars again, there's nothing stopping him and we'd have to come up with and sign a brand new agreement yet again?

Recent news has made it plain that President Trump intends on going through with his much discussed plan of implementing tariffs on many sources of steel and aluminum imports to the US. This seem as good a time as any to ask a question that begs for evidence: Are trade wars good, and who benefits?

There is good reporting out there that analyzes the likely impact of this particular steel tariff, so feel free to find it and use it in your own argument (there are figures the administration has produced and figures that other studies have produced using the same source material). There are also plenty of other tariffs out there throughout history that have been studied and discussed. Because these sources can sometimes conflict, please be aware that your choice of what sources to use may need to be justified.
