The Panama Canal
It would be very hard for anyone today to imagine what the Panama Canal Zone was like in its heyday, which would have been in the 1940s and 50s. It was after the Suez Crisis of 1956 when Egypt took control of its Canal that the whole question of sovereignty over the Panama Canal and the Canal Zone began to change: you could say the whole process of decolonization in the developing world which was strongly backed by the U.S. after WWII, put an end to America’s oldest colony.
