US President Donald Trump has rejected any negotiations with Iran and raised the possibility that the Iran war would only end once Tehran no longer has a functioning military or any ​remaining leadership in power.

Speaking to reporters aboard Air Force One on Saturday, Trump said the air campaign could make negotiations a moot point if all potential leaders of Iran are killed and ‌the Iranian military is destroyed, said a Reuters report.

Trump said US troops could “possibly” be sent on the ground in Iran, but there would have to be a “very good reason.”

Pressed whether he would consider using ground troops to secure enriched uranium at Iran’s nuclear sites, Trump also said it’s a possibility, but not right now.

“We’ll find out about that. We haven’t talked about it. It was a total obliteration. They haven’t been able to get to it. And at some point maybe we will. It would be a great thing but right now we’re just decimating them but we haven’t gone after it,” Trump said.

“But something we could do later on. We wouldn’t do it now,” he added.

Earlier on Truth Social, he posted: "Iran, which is being beat to HELL, has apologized and surrendered to its Middle East neighbors, and promised that it will not shoot at them anymore. This promise was only made because of the relentless U.S. and Israeli attack. They were looking to take over and rule the Middle East. It is the first time that Iran has ever lost, in thousands of years, to surrounding Middle Eastern Countries. They have said, “Thank you President Trump.” I have said, “You’re welcome!” Iran is no longer the “Bully of the Middle East,” they are, instead, “THE LOSER OF THE MIDDLE EAST,” and will be for many decades until they surrender or, more likely, completely collapse! Today Iran will be hit very hard! Under serious consideration for complete destruction and certain death, because of Iran’s bad behavior, are areas and groups of people that were not considered for targeting up until this moment in time."
