The Long View

The United States landed on the moon, then within 50 years fragmented due to a series of wars abroad, political scandals (largely precipitated by either government secrecy or the exchange of money in the political process), and economic mismanagement. By 1992, the U.S. had successfully defeated the USSR (its rival in the so-called “Cold War,” a series of proxy wars, 1945-circa 1992, undergirded by psychological warfare and a race-based caste system); within 25 years the U.S. had also bankrupted itself by transferring specie to the military corporations (or, as they became known, millicorps).

I think this is a cool idea, though not 100% souped with the handling I've given it here. The assumption that the history textbooks of xxx years from now will be written in the same style is a safe bet I think.
