Sure, but the point is that to achieve this standard, a lot of blood was shed and a lot of countries were exploited. Enforcing a uniform culture would almost certainly involve some use of force because people hold their cultural identities very dear to themselves (rightfull so IMO). Robbing them of this identity and enforcing a external one would not go down well at all. Even today, most people who are speak English that were not born in a English speaking country speak another language. So it isn't the case that English has supplanted native languages, but rather has supplemented them. This, despite years of colonial domination.
