A security analyst says it's likely Trump's hardball foreign policy with Ukraine is part of his promise to deliver a peace deal as fast as possible. 

Ukraine's President says he's ready to sign a minerals deal and reach a peace deal only hours after America's decision to pause military aid. 

It also follows a fiery White House meeting between Volodymyr Zelenskyy and Donald Trump. 

A Kyiv-based security analyst Jimmy Rushton told Mike Hosking Trump's been putting a lot of pressure on Zelenskyy to sign a deal without a US security guarantee. 

He thinks the President's found Russia won't budge and it'll be easier to get Ukraine to sign to unfavourable terms.
