French President Emmanuel Macron convened a rare defense cabinet meeting to discuss Iran and its nuclear program amid growing tensions between Tehran and U.S. President Donald Trump. Concerns are rising among European allies that the U.S. or Israel could launch air strikes on Iran's nuclear facilities without a negotiated deal. European powers have been trying to pressure Iran into negotiations, but coordination with the U.S. has been difficult. The Trump administration has focused on a campaign of 'maximum pressure' against Iran, while the Europeans hope to have a new deal in place by August.
