President Donald Trump is finally taking the fight to Vladimir Putin. Sort of. For now. Trump’s deference to Russia’s authoritarian leader has been one of the most enduring geopolitical subplots of the past decade.

Pentagon officials said details were still being worked out, and experts doubted Mr. Trump’s threat of huge tariffs for Russian trading partners.

A White House official clarified to CNN that when the president referred to ‘secondary tariffs,’ he meant 100% tariffs on Russia and secondary sanctions on other countries that buy Russian oil,” per CNN’s Kevin Liptak.
