Trump reviews plan to halt US military aid to Ukraine

Two key advisers to Donald Trump have presented him with a plan to end Russia's war in Ukraine if he wins the presidential election that involves telling Ukraine it will only get more US weapons if it enters into peace talks.

The United States would warn Moscow that any refusal to negotiate would result in increased US support for Ukraine, retired Lieutenant General Keith Kellogg, one of Trump's national security advisers, said in an interview.

Under the plan drawn up by Kellogg and Fred Fleitz, who both served as chiefs of staff in Trump's National Security Council during his 2017-2021 presidency, there would be a ceasefire based on prevailing battle lines during peace talks.

They have presented their strategy to Trump, and the former president responded favorably, Fleitz said. "I'm not claiming he agreed with it or agreed with every word of it, but we were pleased to get the feedback we did," he said.

However, Trump spokesperson Steven Cheung said only statements made by Trump or authorised members of his campaign should be deemed official.

The strategy outlined by Kellogg and Fleitz is the most detailed plan yet by associates of Trump, who has said he could quickly settle the war in Ukraine if he beats President Joe Biden in the November 5 election, though he has not discussed specifics.

The proposal would mark a dramatic shift in the US position on the war and would face opposition from European allies and within Trump's own Republican Party.

The Kremlin and Ukraine's foreign ministry did not respond to requests for comment on the plan.
