My response to that, and I have used it, is that Europe is so fragmented, they HAVE to learn another language. I tell 'em that I can go 3,000 miles coast to coast or 1,500 miles north and south and still be within one country, thus no need for another language. Try that in Europe.
And, English is the new Lingua Franca today and any foreigner would be foolish not to learn it.
And he did admit that, about smaller countries and more borders...
