Niall Ferguson is always worth reading. Here he is in Foreign Policy on “The Age of Upheaval.” He leaves the U.S.A. till last:
The resources available for policing the world are certain to be reduced for the foreseeable future. That will be especially true if foreign investors start demanding higher yields on the bonds they buy from the United States or simply begin dumping dollars in exchange for other currencies.
Economic volatility, plus ethnic disintegration, plus an empire in decline: That combination is about the most lethal in geopolitics. We now have all three. The age of upheaval starts now.
