Move fast and break things" was Mark Zuckerberg's motto in launching Facebook 20 years ago. It seemed the antithesis of management-school custom and practice. But it worked, to be imitated after a fashion by Elon Musk, Jeff Bezos and other digital tycoons with similar success. Donald Trump is now seeing if it works in government.

The smart money in Washington was that after the fiasco of Trump's first term, his second would see a more emollient president, one careful of his reputation. He would reach out, consult, become a peacemaker, in his desperation to become a Nobel president like Barack Obama.
