Today’s Republican Party has made a turn toward foreign-policy isolationism or, less pejoratively, realism and restraint. After Donald Trump shattered the GOP’s omertà about the disastrous Iraq War—a “big fat mistake,” he called it in 2016—Republicans quickly learned to decry “endless wars” and, often quite sensibly, argue for shrinking America’s global military footprint. During the 2020 election, Trump’s supporters touted his refusal to start any new wars while in office (though he got very close).
When it comes to America’s southern neighbor, however, Republicans have grown more hawkish. Party leaders, including members of Congress and presidential candidates, now regularly advocate for direct U.S. military intervention in Mexico to attack drug cartels manufacturing the deadly fentanyl flooding into America. “Building the wall is not enough,” Vivek Ramaswamy said at Wednesday night’s GOP-primary debate. The best defense is now a good offense.
