In 2021, the Biden administration turned down a meeting request with El Salvador’s president, Nayib Bukele, on a trip to Washington, snubbing the self-proclaimed “world’s coolest dictator” for fear a photo op would embolden his attempts to expand his power base.

A little more than three years later, it’s the United States that’s courting Bukele. A high-level delegation led by U.S. Homeland Security Secretary Alejandro Mayorkas, and senior White House and State Department officials, attended Bukele’s inauguration in San Salvador on Saturday to a second term.

The visit — unthinkable until recently — caps a quiet, 180-degree shift in Washington’s policy toward the small Central American nation of 6 million that reflects how the Biden administration’s criticisms of Bukele’s strong-armed governing style have been overtaken by more urgent concerns tied to immigration — a key issue in this year’s U.S. presidential election.

“They’ve realized what he’s been doing works,” Damian Merlo, an American adviser to Bukele who is registered to lobby on the Salvadoran government’s behalf, said in an interview from El Salvador. “If the U.S. is serious about wanting to address the root causes of migration, then Bukele is someone who has actually done it.”
