Redundancy watch

I'm currently using a search form which requires me to choose either a "U.S. State," which is fine, since otherwise I might think I was meant to pick a Mexican state or some other kind; or to choose an "International Country." Why in the world would one feel the need to qualify "country" with "international"? What are these non-International countries which they are worried might be chosen. I believe the idea is to disallow the United States as country choice, but the United States is as international a country as the next, if not more so.
