But don't be too quick to dismiss the idea of Americans learning other languages. Knowing another language enriches you, makes you more valuable. Knowing one of the critical languages makes you dangerous to potential enemies.
I just might start learning Arabic. It won't make me any less of an American, I still speak fluent English. If I knew Arabic, I could annoy and distress the m* f*s that are threatening my country. Yeah, I like that. Other languages are a good thing. It doesn't take anything away from you to learn one.
It seems like our national priority would be to meld these folks into our culture rather than making me fluent in several different cultures that exist in our country, although I do see value in that as a personal learning experience.
