Welcome to the horns of a dilemma...
Trump's Iran dilemma exposes bitter split in president's circle
Kentucky Senator Mitch McConnell said it had "been kind of a bad week for the isolationists" in the party.
"What's happening here is some of the isolationist movement led by Tucker Carlson and Steve Bannon are distressed we may be helping the Israelis defeat the Iranians," McConnell told CNN.
Other warhawks in the party are egging on Trump to target Iran.
South Carolina Senator Lindsey Graham said it was in the national security interests of the US to prevent Iran from obtaining a nuclear bomb. Tehran maintains its nuclear programme is for peaceful, civilian purposes such as energy.
"President Trump understands the threat the ayatollah [
Iran's Supreme Leader Ali Khamenei] presents to us, not just Israel, and that he will, at the end of the day, help Israel finish the job," Graham told Fox News.
Vice-President JD Vance, seeking to bridge the divide, said in a social media post that Trump "may decide he needs to take further action to end Iranian enrichment".
The conflict has pitted the isolationist and hawkish wings of the US leader's party against one another.
