For those who hope that Donald Trump has no views on foreign policy, forget it. Not only does he have a view about America’s role in the world, but it is one shared by many Americans. He may or may not cosy up to Vladimir Putin, have a trade war with China or even build his wall. But on the biggest question of all, from which everything else flows, the question of US responsibility for global order, he clearly has little interest in continuing to shoulder that burden. He aims to put America First, which means we are closer to the end of the 70-year-old US world order

Mr Trump, in this respect, is no anomaly. Pat Buchanan rode “America First” a long way against George HW Bush of New World Order fame in 1992; and after the Iraq and Afghan wars and the financial crisis, it became a national phenomenon. Internationalists such as Jeb Bush and Marco Rubio went nowhere this year; Bernie Sanders joined Mr Trump in attacking global involvement; and Hillary Clinton was hit from all sides for being too internationalist and too wedded to the idea of the US as the “indispensable nation”, the Bill Clinton phrase that encapsulated the thinking of every president from Harry Truman to George W Bush. President Barack Obama was the transitional figure away from that tradition, and Mr Trump’s election is the decisive break. The US is, for now, out of the world order business.

This does not mean a “return” to a mythical American isolationism. This powerful, commercially minded nation has never cut itself off from the rest of the world, not even in the 1930s. What it does mean is a return to national solipsism, with a much narrower definition of American interests and a reluctance to act in the world except to protect those narrow interests. To put it another way, America may once again start behaving like a normal nation.
