To an extent I can agree, but I also disagree. While it is understandably desirable to wish the hegemonic group to maintain dominance in all areas, including language, I feel that there is some short-sightedness going on too. For instance, if and/or when english does not become the dominant primary language, I would want the institutions, mythology, etc of the United States to be able to thrive without it. After all, although our language is dominantly english, we Americans pride ourselves on being based on a set number of ideas, rather than religion, ethnicity, and so forth. As the Coke ad does not diverge from the American ideological foundations (and instead seems to prop it up), I mostly say that this is another piece of good nationalism. I wouldn't wish this "Empire of Liberty" to be so totally reliant upon a language that it falls apart when it is no longer the most spoken. I'd rather it adopt a language as it needs to (although english is hardly going away, it's the most common language of international commerce-which is also a testament to our empire).
