ROME — Italy has confirmed it will not fund the purchase of U.S. weapons due to be delivered to Ukraine, the latest sign that Rome is seeking to place limits on its defense spending. Addressing the Italian parliament this week, Defense Minister Guido Crosetto said Italy had decided against backing the NATO Prioritised Ukraine Requirements List (PURL) scheme, under which nations agree to fund the purchase of U.S. arms which are then transferred to Ukraine.
