Legal and Practical Consequences of a Blockade of Cuba

Headnotes: 

The President has the power to establish a blockade of Cuba under the laws of the United States without further congressional action.

A blockade may be unilaterally established by the United States under international law but its establishment may be questioned within the Organization of American States and the United Nations. In addition, such a blockade could be regarded by Cuba and other Soviet Bloc nations as an act of war.
