If a president of the United States were to sketch out a secret, detailed plan to break up the Atlantic alliance, that plan would bear a striking resemblance to Trump’s behavior.
It would involve outward hostility to the leaders of Canada, Britain, France, Germany and Japan. Specifically, it would involve picking fights over artificial issues — not to win big concessions for the United States, but to create conflict for the sake of it.
A secret plan to break up the West would also have the United States looking for new allies to replace the discarded ones. The most obvious would be Russia, the biggest rival within Europe to Germany, France and Britain. And just as Russia does, a United States intent on wrecking the Atlantic alliance would meddle in the domestic politics of other countries to install new governments that also rejected the old alliance.
Check. Check. Check. Check. Trump is doing every one of these things.
