The offshore American military presence has not put a damper on the long, lively Christmas season in the capital, which, by order of Mr. Maduro, began in October and runs until Jan. 6 – Three Kings Day.

In Paseo de los Próceres, Caracas’s largest avenue, Christmas celebrations are in full swing. Families stroll between illuminated decorations, children pose for photos beside Santa or the Grinch, and vendors sell snacks.
