The English-Speaking World, A Possible Scenario or Nostalgic Nationalism?

From a speculative article in Foreign Affairs

A Future of the English-Speaking Peoples - Lie Back and Think of the Anglosphere, Edoardo Campanella and Marta Dassù , February 21, 2017

Some quotes:

“The Anglosphere’s time may have arrived…

This political community represents six percent of the world’s population, a quarter of global GDP, and 40 percent of total military spending. It boasts some of the highest GDP per capita in the world...

If the Anglosphere comes together as a political project, it could signal the emergence of a new model of globalization, centered on cultural homogeneity, with regional clusters converging around common cultural factors, and without a rigid underlying institutional structure like the European Union…

Nostalgic nationalism will likely reinforce tensions and frictions between regions that are culturally distant, especially when standards of living differ greatly. But it can bring culturally similar countries closer together. Indeed, nostalgic nationalism is already reshaping the global order, but it will not necessarily lead to outright isolationism or conflict. There is room for new forms of cooperation to flourish”.
