After 75 years of progress, was last week a hinge in history?; Washington Post, June 4, 2017

Lawrence Summers, Washington Post; After 75 years of progress, was last week a hinge in history?

"We may have our first post-rational president. Trump has rejected the view of modern science on global climate change, embraced economic forecasts and trade theories outside the range of reputable opinion, and relied on the idea of alternative facts rather than evidence-based truth.

Even for conservative statesmen such as Ronald Reagan, George W. Bush and Henry Kissinger, the idea of a community of nations has been a commonplace...

In service of this theory, the president in the past two weeks renounced any claim to U.S. moral leadership by failing to convincingly reaffirm traditional U.S. security commitments to NATO and abandoning participation in the Paris global climate agreement...

What is to be done? The U.S. president is not America. The world will be watching to see whether Trump’s words and deeds represent an irrevocable turn in the nation’s approach to the world or a temporary aberration. The more that leading figures in U.S. society can signal their continuing commitment to reason, to common purpose with other nations, and to addressing global challenges, the more the damage can be contained. And, of course, Congress has a central role to play in preventing dangerous and destabilizing steps."
