During the 2020 presidential campaign, Joe Biden promised to approach Russia and its irascible President Vladimir Putin with a new sense of toughness and purpose. Now calling the shots in the White House, President Biden appears to have made good on that promise — at least symbolically.

On Tuesday, the Biden administration announced several sets of sanctions against Moscow for last summer’s attempted assassination of the Russian activist Alexei Navalny, a plot that involved the Soviet-era nerve agent Novichok.
