In a 48-hour whirlwind, President Donald Trump went from elated to indignant to triumphant as the fragile Israel-Iran ceasefire agreement came together, teetered toward collapse and ultimately coalesced.

President Donald Trump told ABC News on Tuesday morning he is "not happy" with either Israel or Iran after the opening hours of a nascent ceasefire between the two combatants were marred by reported exchanges.

Iran fired a final wave of deadly missiles at Israel before acknowledging the deal, while Israel said it accepted the proposal because all its military objectives were already achieved.
