United States territorial acquisitions
The Panama Canal Zone was an unorganized US territory located within the Republic of Panama. It was established under the Hay–Bunau-Varilla Treaty in 1903 and disestablished in 1979 under the Torrijos–Carter Treaties. Panama gained full control over the Panama Canal in 1999.
Strom Thurmond
In 1974, Thurmond and Democrat John L. McClellan wrote a resolution to continue American sovereignty by the Panama Canal and zone. Thurmond stated that the rhetoric delivered by Secretary of State Henry Kissinger suggested that the "Canal Zone is already Panamanian territory and the only question involved is the transfer of jurisdiction." In June 1974, Senator Henry M. Jackson informed Chairman of the Senate Armed Services Committee that he had arranged for Thurmond to cosponsor an amendment revising the present export control system and restricting trade with the Soviet Union while granting the Defense Secretary power to veto any export that might "significantly increase the military capability" of either the Soviet Union or other Communist countries. Jackson introduced the amendment after Howard M. Metzenbaum yielded the Senate floor before Majority Leader Mike Mansfield caught on to the proposal and succeeded in preventing an immediate vote.
