We all know Americans like that don't we? One of my cousins. One of my neighbors. One of the secretaries of the office. They are just so full of American hubris and so intellectually rigid that they should just never leave the country. Not good for them, not good for the people they meet and not good for anybody who is going to base what they think the US is like on meeting them.
Those Americans that shouldn't leave the country, they also shouldn't lead the country. The last one that needed to be held by the hand as he went from country to country was George Bush and we saw how that worked out.
