US President Donald Trump is trying again to end the war in Ukraine – not by targeting Russia, but by hitting the countries that buy Russia’s oil.

President Donald Trump opened his remarks alongside NATO Secretary-General Mark Rutte in the Oval Office on Monday by threatening "severe tariffs" against Russia. "We're very, very unhappy with them," Trump said of Russia. "And we're going to be doing very severe tariffs if we don't have a deal in 50 days."

Trump's threat against Russia runs parallel to a Senate-led effort to pass crippling sanctions on countries that buy Russian energy.

U.S. President Donald Trump said he was disappointed but not done with Russian President Vladimir Putin, according to a BBC interview published on Tuesday, hours after Trump announced new weapons for Ukraine and threatened Russia with sanctions.

President Donald Trump and his supporters point to encouraging economic indicators to argue that concerns about his tariffs are overblown. Skeptics, however, say it’s too soon to declare that all’s well.
