Diplomats and experts described various scenarios if the U.S. decides to walk. They range from the U.S. ceasing direct aid to Ukraine — but allowing European nations to pass on critical American intelligence and weapons to Kyiv — to Trump banning transfers of any American technology, including components or software in European weapons.Any withdrawal of U.S. military aid to Ukraine could create serious difficulties for Europe, analysts and diplomats told The Associated Press. Kyiv’s ability to keep fighting would depend on European political will to muster money and weapons — and how quickly the gaps left by Washington can be filled.If it were easy, Europe would “already be doing things without America,” said a European diplomat, who spoke on condition of anonymity to discuss the sensitive matter.

No new U.S. aid package for Ukraine has been approved since Trump came into office, even as European nations have collectively provided Ukraine with more aid than Washington, according to the Keil Institute.

Europe has contributed around $157 billion, some $26 billion more than the U.S., although Washington slightly outpaces Europe when it comes to military aid, the Germany-based institute said.Lula on Wednesday stopped over in Moscow on his return from a state visit in China, where he told journalists: “When I get to Moscow, I’m going to try to talk to Putin. It won’t cost me anything to say, ‘Hey, comrade Putin, go to Istanbul and negotiate.”

They did not meet, but the Kremlin said he and Putin spoke by phone. The Kremlin said Lula referenced the peace talks and “intends to do everything in his power to ensure their success.” It said Putin expressed gratitude for efforts to find ways to resolve the conflict.The Kremlin did not mention any discussions of Putin’s possible travel to Istanbul.

Lula’s communications department said the Brazilian leader encouraged Putin to attend the talks, acknowledging, however, that it’s the Russian leader’s prerogative to select the delegation for the meeting.The Kremlin on Wednesday said Putin’s aide Vladimir Medinsky will head the Russian delegation, which will also include Deputy Defense Minister Alexander Fomin, Deputy Foreign Minister Mikhail Galuzin and Igor Kostyukov, chief of the General Staff’s main directorate.
