The new political divide

AS POLITICAL theatre, America’s party conventions have no parallel. Activists from right and left converge to choose their nominees and celebrate conservatism (Republicans) and progressivism (Democrats). But this year was different, and not just because Hillary Clinton became the first woman to be nominated for president by a major party. The conventions highlighted a new political faultline: not between left and right, but between open and closed (see article). Donald Trump, the Republican nominee, summed up one side of this divide with his usual pithiness. “Americanism, not globalism, will be our credo,” he declared. His anti-trade tirades were echoed by the Bernie Sanders wing of the Democratic Party. America is not alone. Across Europe, the politicians with momentum are those who argue that the world is a nasty, threatening place, and that wise nations should build walls to keep it out. Such arguments have helped elect an ultranationalist government in Hungary and a Polish one that offers a Trumpian mix of xenophobia and disregard for constitutional norms. Populist, authoritarian European parties of the right or left now enjoy nearly twice as much support as they did in 2000, and are in government or in a ruling coalition in nine countries. So far, Britain’s decision to leave the European Union has been the anti-globalists’ biggest prize: the vote in June to abandon the world’s most successful free-trade club was won by cynically pandering to voters’ insular instincts, splitting mainstream parties down the middleNews that strengthens the anti-globalisers’ appeal comes almost daily. On July 26th two men claiming allegiance to Islamic State slit the throat of an 85-year-old Catholic priest in a church near Rouen. It was the latest in a string of terrorist atrocities in France and Germany. The danger is that a rising sense of insecurity will lead to more electoral victories for closed- world types. This is the gravest risk to the free world since communism. Nothing matters more than countering it.
