CAMBRIDGE, Mass. — “Effective immediately, I am canceling the last administration’s completely one-sided deal with Cuba.” Thus said President Trump on June 16 in Miami to wildly enthusiastic applause from the remaining veterans of the failed 1961 Bay of Pigs invasion of Cuba. Yet, in practice, Obama administration policies toward Cuba remain in effect. President Trump has set up political, bureaucratic and diplomatic bargaining for months to come.

Through its actions since Jan. 20 and its policy announcements on June 16, the Trump administration has ratified bipartisan policies of engagement with Cuba. These include United States-Cuban military collaboration on the perimeter of the Guantánamo base, collaboration by air and sea to interdict and punish drug trafficking, Coast Guard and military all-purpose collaboration on the Straits of Florida, and security collaboration to stop undocumented migration, expanded in January consistent with President Trump’s preferences.

The Trump administration has ratified Obama administration immigration policy toward Cuba, which ended privileged status for undocumented Cuban migrants who are to be treated now like all similarly situated migrants. It has also left intact diplomatic relations, United States commercial flights to Cuba, 12 Obama administration categories of authorized group travel to Cuba — even cruise ships — as well as unfettered financial remittances from the United States to Cuba and agricultural exports to Cuba, worth well over $5 billion since President George W. Bush authorized them in 2001.
