Franklin Delano Roosevelt on Border Walls

"What I seek to convey is the historic truth that the United States as a nation has at all times maintained opposition --clear, definite opposition-- to any attempt to lock us in behind an ancient Chinese wall while the procession of civilization went past. Today, thinking of our children and of their children, we oppose enforced isolation for ourselves or for any other part of the Americas."

— FDR, speech on "The Four Freedoms," Jan 6, 1941
