I've always wondered what "illegal" means in this context? Is it designed to just be a pejorative, or something incendiary? When is an invasion "legal"? I can't really think of any case where any kind of recognized body of law (especially one that both constituents would recognize) would impose legality on an invasion, so it seems that people say "illegal" in much the same way that "legal" has become a stand-in in our society for "moral".
Should I read it as "immoral invasion"? Leaving aside whether it is or isn't, at least that framing makes sense, because you can meaningfully debate the morality of an invasion, but I can't understand how you could debate legality (except perhaps within the country's own internal framework of laws, like if a president declared a war without going through the proper legal channels).
