Wait a second - do you have a trustworthy reference? Are you (or the media) suggesting that the US managed to infiltrate European air traffic control and hoaxed the bolivian plane to land?

I would not trust those official announcements, more likely that we'll have to dissect them carefully to see what they are not saying, e.g.: "We did not officially refuse them access to our airspace." (But the airspace was so crowded that due to security reasons no further planes could be allowed).
