Since 2017, more than one million Central Americans have made their way to the U.S. southwestern border, triggering a disjointed but brutal crackdown by the administration of President Donald Trump. Although the combination of tighter border controls and the coronavirus has reduced these flows, they will resume when the Covid-19 lockdowns lift.

The resulting tensions could destabilize one of the worldā€™s most tightly woven bilateral relationships, jeopardizing cooperation on everything from counternarcotics to water rights and the prosperity that closer ties have underpinned on both sides of the border.
