Mexico has launched a massive deployment of 10,000 troops to cities and towns on the border with the United States. Videos and photos posted on social media by Mexico's Secretariat of National Defense (SEDENA) showed military and National Guard troops lined up boarding transport planes and rows of army trucks rolling out in the predawn darkness Feb. 4 from army bases in Mexico City, Tlaxcala and other cities. Large contingents were also mobilized to Mexico's southern border in the Yucatan. The response—dubbed "Operativo Frontera Norte"—is part of an agreement reached the previous day between US President Donald Trump and Mexican President Claudia Sheinbaum postponing trade tariff threats for a month.

Trump signed executive orders Feb. 1 to impose 25% tariffs on Mexico and Canada, and a 10% import tariff on China. The tariffs, which include a carve-out of a lower 10% levy on Canadian energy exports, were imposed under a "national emergency" exemption to the US-Mexico-Canada Agreement (USMCA), citing a crisis of illegal migration and drugs.
