It turns out that sovereignty is basically something you have if you say you have it and people agree. The US is clearly attempting to expand its claim of sovereignty with laws of this sort. Most of the rest of the world will probably accept it. Some places may not, and might pass their own "American Invasion Act". "International Law" isn't a real thing, because there's no single body with the necessary monopoly on force to implement and enforce it. There is merely the cooperation and posturing of a variety of powers who use a combination of influence and force to secure their interests. Sometimes, nearly all of the major powers agree on something, and then it gets written up and followed closely enough to look like law, but it isn't. (One could make the same argument about individual State laws in places where the State is either too weak or too corrupt to actually enforce their laws in anything resembling impartiality, but that's beyond the scope of this topic I think)
