we would resent Americans for two reasons because:
- we speak the same language but live a different culture. It's like comparing Aussie Rules to Gridiron. We find so many of the things they do just so "American", implying that it is too Yankee for us, should be avoided and instead therefore go for something more Aussie. What steams up this more is that so much of our own culture is being bombarded with American culture. A McDonalds store is ever around the corner. TV is saturated with US imports. Stuff we buy at the supermarket originates in America (and even those 'Australian' ones such as Arnotts and Aeroplane are US owned). because we see US stuff taking over our lives, we are patriotically outraged, but at the same time we cannot help it because often their good products can be efficient, cheap, convinient and even great.
- their government and all of that star-spangled carry-on. the opinion we may have on their government tends to mean we think the same of the people.
but however much we may hate them, we're with them for the long haul, not only politically but economically as well. i think most, if not all of us would not want to see the Australia-US alliance go away either. just maybe not as strong.
