Is India primarily an Asian superpower or an Anglosphere democracy? President Trump’s recent visit there — he joined Prime Minister Narendra Modi in India’s largest cricket stadium, a return match after Modi’s rally at a Houston stadium last year — dramatizes what may be the single most important question of the 21st century.

The Anglosphere is united by the English language, the common law, respect for private property and a tradition of constitutional liberty going back, ultimately, to the Magna Carta — the site of which in Runnymede, incidentally, was marked until recently by only two memorial stones, one raised by Americans and one by Indians.
