President Donald Trump issues Russian President Vladimir Putin a 50-day deadline to end Ukraine war or face 100% tariffs, prompting skepticism from the EU's chief diplomat and Kyiv's mayor over 50-day timeframe.

But his frustration with Putin has grown. Last week, the president said the United States was taking “a lot of bullshit” from Putin. Today, he authorized a significant shipment of U.S. defensive weapons to Ukraine via NATO and threatened Russia with new tariffs if the war does not end 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.

The Kremlin said on Tuesday that U.S. President Donald Trump's recent statements, including a threat of sanctions on buyers of Russian exports, are serious and require analysis.

NATO Secretary General Mark Rutte warned India, China, and Brazil of potential secondary sanctions if they continue trade with Russia. Rutte urged these nations to pressure Putin for peace talks.

“Putin will not negotiate as a loser,” one of his longtime associates tells TIME by phone from Moscow. “He knows that winners don’t get punished, and if he wins, all of this” — the sanctions, the tariffs — “will go away.”

Melania Trump has highlighted Russia's continued attacks on Ukraine in private conversations, President Trump said on Monday.

You might want to call Vladimir and say, ‘Hey, friend, we are still buying stuff from you, but you have got to get serious when it comes to these negotiations on the cease-fire or a peace

President Trump has effectively handed Vladimir Putin an extraordinary green light: 50 days to finish off his brutal summer offensive in Ukraine before facing any consequences.
