Right, it made them nervous but, in the end, there was no major activity taken. I didn't know it there are any international regulations about it, or treaties around it. This is one subject Google is not very helpful with, though I may not know the correct terminology to search effectively with. In the NK missile tests, Japan (rightfully) was pretty pissy but the end result has been largely nothing. My guess, and it is only a guess, is that it'd be much the same if, for some reason, we sent a missile through space and over Russian territory. Though, I guess, Russia really wouldn't have much ability to sanction the US or enforce said sanctions. We don't really require anything from Russia and they are not close allies with anyone we do depend on.
