Canadian Prime Minster Justin Trudeau had a strong reaction to the Trump administration imposing tariffs on steel and aluminum from Europe, Mexico and Canada.

Trump had originally imposed the tariffs in March -- saying a reliance on imported metals threatened national security -- but he exempted Canada, Mexico and the European Union to buy time for negotiations.

As of June 1, tariffs will no longer be suspended for steel or aluminum imports from those countries.

In an interview that aired on "Meet the Press" on Friday, Trudeau slammed the claim that the new tariffs will enhance U.S. national security.

"Our soldiers who had fought and died together on the beaches of World War II and the mountains of Afghanistan, and have stood shoulder to shoulder in some of the most difficult places in the world, that are always there for each other, somehow — this is insulting to them," Trudeau said.

"The idea that the Canadian steel that's in military, military vehicles in the United States, the Canadian aluminum that makes your, your fighter jets is somehow now a threat?" he continued. "The idea that we are somehow a national security threat to the United States is quite frankly insulting and unacceptable."

Canada will impose tariffs against imports of steel, aluminum, and other products from the US – we are imposing dollar for dollar tariffs for every dollar levied against Canadians by the US. — Justin Trudeau (@JustinTrudeau) May 31, 2018

Canada will also challenge these illegal & counterproductive measures under NAFTA Chapter 20 and at the WTO. It is simply ridiculous to view any trade with Canada as a national security threat to the US and we will continue to stand up for Canadian workers & Canadian businesses. — Justin Trudeau (@JustinTrudeau) May 31, 2018

On "Fox & Friends" on Saturday, Pete Hegseth said it's one thing to oppose tariffs, but it's another to invoke the military.

"As someone who's stood shoulder to shoulder, literally, in Afghanistan with troops from Canada -- many of which are wonderful -- this type of back and forth on trade has nothing to do with an alliance that's been around for a long time," Hegseth said. "You can do better than that."
