That's very true, Rebecca, but part of what McGrath was saying, I think, is that one of the unusual things about the US, as a country of immigrants, is that all of the countries we all came from, their history is our history. All that history, from so many different countries, etc, is American history too. Where we all came from made us what we are. (This is not in the least meant ot discount the thousands of years of history of the more native civilisations and the native Americans, of course...)
