There's another warning from President Donald Trump to Cuba in the wake of Nicolás Maduro's ouster in Venezuela. Cuba is a close ally of Venezuela and a major beneficiary of oil shipments from Venezuela. But Cuba has been cut off from shipments as U.S. forces seize tankers in an effort to control the production, refining and global distribution of Venezuela's oil products. Trump used a social media post Sunday to urge Cuba to make a deal before, as he put it, “IT IS TOO LATE.” He didn't explain what kind of deal. Cuba has long been kept economically afloat by Venezuela.
