While the US has been involved in conflicts where it seems that they have questionable motives, I think the post had more to do with the US involvement in the World Wars, which simply did not have any questionable motives. This is where if I were one of the stereotyped "arrogant Americans" you Europeans seem to hate I would make a comment like "without us you'd still be eating wienerschnitzel with Adolf's grandchildren," but I'm not.
Also, if you're suggesting the US is stealing oil and money from Iraq, they simply aren't doing a very good job considering the gas prices remain high and the deficit is ever increasing.
