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?
