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.”

President Trump has long boasted of his friendly relationship with Putin, and after taking office in January repeatedly said that Russia was more willing than Ukraine to reach a peace deal.

In addition to the tariff threat, European allies plan to buy military equipment and then transfer it to Ukraine.
