Donald Trump’s threat to shut the U.S. border if Mexico does not halt all illegal immigration has exposed the limitations of the new Mexican government’s strategy of trying to appease the U.S. president as he gears up for re-election.

Amid a surge in migrant detentions at the southwest U.S. border, Trump on Friday said he would close the 2,000-mile (3,200-km) frontier, or sections of it, during the coming week if Mexico did not halt the flow of people.

Casting the government under leftist President Andres Manuel Lopez Obrador as the villain in his struggle to curb illegal immigration to the United States, Trump returned to a signature theme of his 2015-2016 presidential election bid.

His words were a slap in the face to Lopez Obrador, who has refused to answer back to provocative comments from Trump. Instead, the Mexican leader has worked to cement his powerbase by combating poverty with welfare handouts and lambasting his predecessors as corrupt.

On Friday, Lopez Obrador again said he would not quarrel with Trump, invoking “love and peace” and repeating his commitment to curbing migration.

However, for former Mexican foreign minister Jorge Castaneda, Mexico faces “incredibly damaging” consequences if Trump does order “go-slows” at the border, which would pitch Lopez Obrador into uncomfortable new territory.

“He’s totally unfamiliar with international affairs. He’d prefer not to have to worry about these things,” Castaneda said, noting that the U.S. president had tested many governments. “Nobody’s been able to find a way to manage Trump. It’s a mess.”
