I already do and so do my kids. However, we are not compeled to do so by the United Nations, (at least not yet and we'd like to keep it that way), but only by personal desire and economic advantage. Not unlike an Englishmen speaking French, German and/or Italian to increase the sales territory of his company or the utility of his trade. The operative words here are "compelled" and "personal desire". If you think that it will be the "Gringo", (of which I am one, despite the latin handle "elbucko") then you know very little of the demographic dynamics actually taking place here in the Southwestern United States. It is actually the Spanish speaker that is learning English, more than the English speaker is learning Spanish. In the fullness of time, Mexico will be a state of the US. Not in my lifetime, but probably in my kids.
England, on the other hand has a different problem, it's not really "European" in culture. I have been fortunate to have spent considerable time in the UK and find it more like America than either Austrailia, New Zealand, or Ottowa and Quebec Canada. A decorated RAF Group Captain, of fighter pilot renown, once told me that the biggest mistake that England made after WWII was not to petitition the US Congress for the UK to become the 49th state. He wasn't kidding. He had trained to fly fighters in Oklahoma, USA in 1940-41. He had travelled extensively in the Us and found it more like English culture than other English speaking countries. He said he did not want to be a European, even though the geographical proximity dictated such. In a semi-prayer, he intoned that the Almighty would be generous, indeed, if He would move the British Isles about 3,000 miles to the So. West.
I could go for that, if the UK would let the socialists off in Europe, before moving the island west.
By the way, I am not one of those Americans, that you seem so concerned about, that worry about whether the world likes us or not. I am one of those Americans that dosen't care at all what the world thinks. Even Europe.
