Assumptions that the Great Republic must inevitably spiral into economic and strategic decline - so like the chatter of the late 1980s, when Japan was in vogue - will seem wildly off the mark by then.
Telegraph readers already know about the "shale gas revolution" that has turned America into the world’s number one producer of natural gas, ahead of Russia.

"The US was the single largest contributor to global oil supply growth last year, with a net 395,000 barrels per day (b/d)," said Francisco Blanch from Bank of America, comparing the Dakota fields to a new North Sea.
Total US shale output is "set to expand dramatically" as fresh sources come on stream, possibly reaching 5.5m b/d by mid-decade. This is a tenfold rise since 2009.
