It’s not illegal. The problem is that there’s no court that could meaningfully adjudicate such a suit. International law doesn’t have almost any teeth. If you’re not a US citizen, you don’t have standing to sue the US government from within the US. If you try to sue the US in another country, there’s no punishment they can hand down that the US has to abide.
