@Jim Watson
Maybe I was a bit over-sensitive. After re-reading your post, I assume your main point was to mention the higher need for knowing foreign languages in Europe compared to the US. At first I was a bit hurt and felt you belittle European countries.
The language barrier lets pass misunderstandings easily. I've already experienced this and have hurt some feelings unintentionally. It's important to know this in multi-language and international communication. After some time I've learned: If I'm in doubt, the guy from the foreign country means what is the best of all possibilities. And I've told the guy from abroad they should please assume so vice versa.
