President Trump and his team, including CIA Director John Ratcliffe, told them to stop. In discussions between US intelligence, Ratcliffe, and Mossad leadership, there was a question of whether to stop the conflict or to continue. Ratcliffe emphasized that the president gave his word and his order was to commence a ceasefire.
The ceasefire remains in effect and as leverage, the US has said they would pull intelligence cooperation should Israel continue a bombing campaign against Iran. This kind of leverage was also employed in Ukraine to assist in gaining a ceasefire in that conflict. After the call with Ratcliffe, Mossad backed down.
The 12 Day War, as Trump has called it, came to an end after the US engaged in a bombing campaign to target Iran's top nuclear facilities at Fordow, Natanz and Isfahan. That bombing effort was carried out on Saturday night and fourteen 30,000 pound ordinances were dropped on those sites. Tomahawk missiles were also deployed from submarines off the coast.
After the undertaking, Trump congratulated both sides, including the Iranians, yet on Tuesday, he was forced to slap down both sides who were behaving like a couple of children who were acting out. Following the cessation of hostilities, Israel's home front command lifted all restrictions that were put in place during the 12 Day War.
Trump never said he was against the use of the American military when necessary, but what he opposes is forever wars, regime change operations. These kinds of operations have been pushed by Senator Lindsey Graham, John Bolton, and pundits like Mark Levine.
This engagement in the 12 Day War, per Trump, was toward the objectives of America and in the interests of the American people, as was bringing it to a swift and decisive close.
