A connected world?

In 1945 President Roosevelt rejected isolationism and “America First.”  Here is what Roosevelt said:

     We have learned that we cannot live alone, at peace; that our own well-being is dependent on the well-being of other nations far away.  We have learned that we must live as men, not as ostriches, nor as dogs in the manger.  We have learned to be citizens of the world, members of the human community.  We have learned the simple truth, as Emerson said, that “The only way to have a friend is to be one.”

That belief, however imperfectly carried out, guided American policy approximately the last 75 years.  Now we are embarked on a new policy, full of distrust and anger.  I don’t believe it will work.
