I'd have thought that this would have been seen as en encouraging affirmation that Spanish-speaking Americans actually saw the USA as a country to feel loyal towards. I rather think that is the way this kind of thing would be regarded in most sensible countries, if it happened there. The reaction to it voiced by Bush sounds undignified and oddly insecure.

The reason apparently given for changing that line about "the rockets red glare" and so forth, I suppose, reflects the fact that a lot of Americans evidently assume that the rockets and bombs being mentioned in the song are American rockets and bombs, and are being celebrated. In fact, of course they are British missiles aimed at defiant Americans, which is what the song is all about. The replacement line expresses admirable sentiments, though it is less colourful, but maybe it's less liable to be misunderstood.

Incidentally, there's a story that the tune is one originally made by Turlough O'Carolan. True or not, it's an indication that it's a pretty good tune, for the story to be credible. I wonder now if Mr Bush would object if someone translated it into the Irish and recorded it?
