Well, I don't know how to argue with that sort of chauvinism, so I'm not likely to continue this discussion. Of course "ivory coast" is english, but so is "cote d'ivoire" (and "costa rica" and "sierra leone" and "los angeles" and all sorts of other words we borrowed from other languages.) Ever heard of a guru? The english hadn't, until somewhere around the 16th century, but now that word is as English as fish n chips! Again, I suggest you do some reading on how language evolves. English is as english does.
