How does Panama view the Canal?
As a non-exploitable natural resource that will eventually return to its natural state as an unused water-way.
As an income-losing problem inherited from the U.S.
As a cash-generating passage, as long as it is cheaper for ships to round South America than go through the Canal.
As an exploitable natural resource, even though it is partially man-made.
As an unpleasant and unprofitable legacy of U.S. domination throughout central America.
