President says 'Iran cannot have a nuclear weapon,' advises restraint on Ukrainian targeting of diesel

On questions about Iran and the Ukraine conflict, the President said succinctly, 'Iran cannot have a nuclear weapon,' and added that Tehran had 'been calling constantly' to seek a deal. He framed his stance as conditional: he would not accept 'a deal that's no good.'

The President also told reporters he had advised Ukrainian President Volodymyr Zelensky to avoid targeting diesel infrastructure, saying 'Don't hit diesel fuel because that's hurting... That's hurting the world.' He presented that as a request to limit certain targets to avoid global shortages but did not provide operational details, military guidance, or confirmation of any change in Ukrainian targeting policy.
