Arnett is an American citizen, and for more than 15 years, at least according to this NYTimes article I found in a quick search. The info is near the bottom of the articleFive Years Later, the Gulf War Story Is Still Being Told

Thanks for link Five Years Later, the Gulf War Story Is Still Being Told.
How arrogant he was then (and now):
The New York Times May 12, 1996: Arnett states: "If we'd had the immediacy in Vietnam that we had in the gulf war, it would have changed history," said Mr. Arnett, 61, who was the only Western correspondent in Baghdad for most of the war. "The Vietnam War could not have lasted as long as it did."

Perhaps finally in this case his current outrageous statements will change his own history.
