Trump’s threats of secondary tariffs are “never going to go anywhere” as long as he is unwilling to impose costs on Moscow directly, Keir Giles, a senior fellow at the London-based Chatham House think tank, told NBC News Monday.

Russia continued its nightly bombardment of Ukrainian cities overnight into Tuesday, after President Donald Trump said the U.S. would send military equipment to Kyiv.

Trump also revealed that Putin had recently offered to assist in mediating between Israel and Iran during their brief June conflict — an offer he declined. “I said, ‘No, no, you help me get a settlement with you, with Russia,’” Trump recounted. “And I think we're going to be doing that too.”

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

Trump agrees to sell billions in U.S. arms to NATO countries including Germany, Finland and Denmark and others for quick distribution to Ukraine, following his ultimatum to Putin on peace talks.

The US president had asked his Ukrainian counterpart whether he could hit military targets deep inside Russia if he provided weapons capable of doing so.

The president left the door open for talks with his Russian counterpart but complained about Russia’s continued aerial attacks on Ukraine.

President Donald Trump will meet with NATO Secretary-General Mark Rutte to announce plans to sell weaponry that they can then pass to Ukraine for its war with Russia.
