Premise: The Cuban Embassy in Washington, DC, is the diplomatic mission of Cuba to the United States of America. It is located at 2630 16th Street Northwest, Washington, D.C., in the Adams Morgan neighborhood. The building was originally constructed in 1917 as the Cuban embassy, and served in that capacity until the United States severed relations with Cuba in 1961.
Hypothesis: The severing of relations in 1961 took days to implement.
