[Edit] Ok, I see the parent comment is an uncited quote of the Wikipedia page "United_States_embargo_against_Cuba." Like I said below, Wikipedia is oddly lacking in a citation for this action by "Eisenhower's government."
> Eisenhower's government refused to export oil to the island
I did a hunt for a cite to support this claim, but did not find one. I searched national archives for executive orders [0, 1] and didn't find anything. The Wikipedia pages that have statements like "In June 1960 a key incident occurred: Eisenhower's government refused to export oil to the island" [2] and "This nationalization of property resulted partially from U.S. President Dwight D. Eisenhower's decision to cancel all oil exports to Cuba." [3] are curiously lacking in a citation.
I wish I still had my copy of The Prize which I recall had excellent footnotes and references.
