U.S. President Donald Trump said hours before Israel announced “pre-emptive strikes” on Iran on Feb 28 that Washington had not made a final decision on military action and that additional talks with Tehran were still expected, even as he complained that Iran was not negotiating to U.S. satisfaction and reiterated that Iran cannot have nuclear weapons. After the strikes were reported, U.S. participation was confirmed by U.S. officials cited in media reports, escalating fears of a wider regional conflict.
