The administration’s rush toward peace talks with Russia on the war in Ukraine has raised concerns over the U.S. commitment to the region’s security.

President Donald Trump and Canadian Prime Minister Justin Trudeau spoke by phone on Saturday, during which the two leaders discussed the war in Ukraine and fentanyl reduction efforts at the United States’s northern border.
