Uncertainty surrounds the trade war touched off by President Trump’s tariffs. But some of the basics are taking shape.

According to President Sheinbaum, Mexico has cut a deal with the U.S. to delay the tariffs. Under the deal, she said Mexico is sending another 10,000 members of its national guard to the southern border to combat drug traffickers, while the U.S. has agreed to do more to prevent the trafficking of high-powered weapons to Mexico.

The move likely will trigger retaliation and risk igniting a trade war that could cause broad economic disruption for all countries involved.
