Technically, all that's being claimed is that the USA has whistleblowers. Grutsch has said before that other countries also have UFO retrieval programmes. So if we suspend disbelief for a moment and assume there's real craft flying around, all it'd take for this current set of events is if the USA had a monopoly on whistleblowers. Given that most famous whistleblowers in recent years have been American this doesn't seem unlikely. Five Eyes has five governments in it, but only the USA had someone who went to the press. The US Government is both very large so more people can leak things, and very well funded, so more chance of secret programmes, and (IMHO) has a civic-minded culture in which people are more inspired by things like the Constitution and stated cultural ideals than in other countries.
