Rising threats to the global commons combined with the economics of war, peace and prosperity means that the long term-strategy for a stable, sustainable planet and a successful America is to bind the world even closer together. The U.S. should be fostering trade relations that create jobs. It should support scholarships and visas for people from the world over to travel to the U.S. for education
and to build global economic ties. And it should embrace global agreements from the International Law of the Sea through the Paris Accords. Going in the other direction will do harm the rest of the world but simply hobble the U.S. The idea that America can be great only by making others worse off is the thuggishness of the schoolyard outcast.
