I don't doubt they love America, but they certainly are not pro-Bush or pro-our response to terror
"Point of No Return," perhaps their most political song to date, deals with America's response to terrorism. Le Bon said the message is that rather than bombing people, "you've got to try and make the world a fairer place."
They've never been terribly political though so rather then chalk them up to radical lefties, which for some reason I rather doubt, I would think naive like many Americans in the squishy middle is probably more accurate, but that is just a guess based on their history and hearing them talk(they were never very serious about anything in their music).
OH, and Simon is married to a woman of middle eastern decent and I believe they live in France so...well, just something to consider. Rio was written a LONG time ago, before he met his middle eastern wife and before he resided full time in France. Point of no return is much more current and probably more reflective of, at least Simon's attitude, toward our country today. Could give a flip less personally, but I don't think we should falsely give them the status currently of pro-US.
...the peaceniks need to be telling the Islamonazis that they are wrong to try to change the world with radicalism and bombs. Bombing terrorists to make the world a safer place is not a shameful decision. It may be a difficult decision but can be a valid response.
All that is needed for evil to succeed is for good men to do nothing.
