Every day, the president’s behavior becomes more worrying. One day he demeans a federal judge who challenges him; the next day, without evidence, he accuses the media of hiding illegal voting or acts of terrorism. His lack of respect for institutions and truth pours out so fast, you start to forget how crazy this behavior is for any adult, let alone a president, and just how ugly things will get when we have a real crisis. And crises are baked into this story because of the incoherence of President Trump’s worldview.

How so? The world today is more interdependent than ever. The globalization of markets, the spread of cellphones, the accelerations in technology and biology, the new mass movements of migrants and the disruptions in the climate are all intertwined and impacting one another. As a result, we need a president who can connect all of these dots and navigate a path that gets the most out of them and cushions the worst.

But Trump is a dot exploiter, not connector. He made a series of reckless, unconnected promises, not much longer than tweets, to get elected, and now he’s just checking off each one, without thinking through the linkages among them or anticipating second-order effects.

It is a great way to make America weak — and overstretched — again.

Where do I start? Trump wants to get tougher with China on trade and security. That’s not crazy. But how would I do that? I’d organize an alliance of Pacific trading nations that surround China and enlist them in a trade pact that supports U.S.-style rule of law, greater market access for U.S. intellectual property and products and promotes U.S. values — as opposed to China’s. I’d call it the Trans-Pacific Partnership, or TPP for short.
