The president still has time to avoid the economic damage, but who knows how much political damage he's already done?

Is Trump's anti-immigration position deeply held or just a way of getting the vote out?
Trump's new United States Mexico Canada Agreement mostly maintains the NAFTA status quo, but it sets new mandates for cars made in Mexico and Canada.
Canada holds the upper hand, as the Trump administration and Mexico rush to finalize new trade deal before Friday's critical deadline.
Andrés Manuel López Obrador's populist campaign promised to tackle corruption, impose price controls, and rewrite NAFTA.
The president's trade policy makes as much sense as Canadian Bacon, the farcical 1995 film about a trumped up war against Canada.
Justin Trudeau and others condemn Trump's protectionist tactics, then respond with protectionism of their own.
