A. Recommended Action
The President should close all United States ports to any ship on a continuous voyage to or from Cuba.
Alternative II
The President should close all United States ports to any ship that on the same continuous voyage carried or carries to Cuba items on the COCOM list.
Alternative III
The President should close all United States ports to any ship that on the same continuous voyage carried or carries to Cuba items on the positive list under Regulation T-1.
Alternative IV
The President should close all United States ports to any ship that on the same continuous voyage was used or is being used in Bloc-Cuba trade.
The President has all the necessary legal authority to carry out the above recommendations without new legislation. A small supplemental appropriation for the Department of Agriculture might have to be included in the budget to pay for shipping in U.S. bottoms.
The President has adequate legal powers to adopt more restrictive policies than those recommended above. There has been some talk, for example, of closing U.S. ports to the ships of any country which permits its ships to go to Cuba. Others have mentioned the possibility of closing territorial waters of the U.S. to such ships, or denying them use of the Panama Canal.
These proposals are not recommended.*
