"Why learn another language, just go to France or Germany ,or Spain,or....."
You make my point exactly. You all speak English (though some of your posts are stretching my point a tad), so why waste my precious grey cells learning your languages?
Incidentally, you say that the world speaks English because of the US.
But then you must ask yourself why the Yanks mangle the English language and not the French?
Because once again the French overestimated the efficacy of their military might, and we kicked your @rse.
