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.

Trump spent his final day at NATO disputing intelligence that said U.S. strikes on Iran's nuke facilities set the country back only by months.

The head of the Israel Defense Forces said Tuesday that “the campaign against Iran is not over” as a ceasefire between the two countries went into effect. President Donald Trump also vowed that Israel will not attack Iran and told Israel to bring its pilots home.
