The US remains adamant it is going to win a war in Iran swiftly, even as it refuses to rule out any options, including boots on the ground.
Israel has launched a wave of strikes in the Iranian capital of Tehran overnight.
More than 1,700 people have died in the Middle East since the conflict started.
US Secretary of War Pete Hegseth says today will be the most intense day of strikes on Iran.
But, questions remain over what the end to the conflict looks like, following a media conference by US President Donald Trump yesterday.
Oil prices have come down, after the President indicated the war may end sooner than the original time frame of four to five weeks.
But as New York Times national security correspondent David Sanger explains, President Trump's statements were at times contradictory.
