IT'S NOT just Donald Trump. The United States has a long record of negotiating international agreements and then running away from them. The rest of the world has an equally long record of heaving a sigh of regret, telling the Americans it will be happy to have them back when they get over it, and carrying on without them. It will do it again over the Paris accord on climate change.
We have had many expressions of synthetic shock since Trump finally announced that he was abandoning the climate accord last week, after wringing every last drop of drama out of his totally predictable decision. Then we had the equally predictable affirmations from everybody else that they would carry on regardless. It's all as stylised and traditional as a Noh play.
The tradition actually dates back to the early 20th century, when the United States was the prime mover in creating a new international institution to prevent war, the League of Nations, at the end of the First World War -- and then refused to join it. The League could probably not have avoided World War II, even if the US had been a member, but its absence certainly didn't help.
Then came a longish period, from the foundation of the United Nations in 1945 to the arms control agreements of the 1960s and 70s, when American leadership actually did make the world a safer place. But by 30 years ago it was back to the bad old ways, with the US not signing (or signing and then "unsigning") the UN Convention on the Law of the Sea, the International Criminal Court, and the Kyoto Accord on Climate Change.
In each case, the rest of the world just went ahead and put the treaty into effect anyway -- and in no case did the American defection destroy the deal. It's already clear that Trump's decision will not sabotage this deal either. The other major powers will all stick with the commitments they made in Paris 18 months ago, because they are all really frightened by what will happen if they don't.
