exactly, like for example Arabic, it is a real pain in the butt to learn; however, if you really want to learn it, you can fool even native speakers(like John Walker Lindgh did)>EDIT: Most Americans who don't truly want to learn a language would not be interested in pronunciation, and end up with a bad dialect of their own. I'm talking about people learning languages in general, not just Americans, especially when they are as grammatically hard as English or other similar languages.
