Jake Sullivan, Biden discussed possibility of hitting Iran nuclear program: report

The president was reportedly presented with a series of scenarios and response options during the meeting, though sources told the outlet that Biden has not made any final decisions regarding the information he was given. 

Biden repeatedly warned Israel against hitting Tehran's nuclear program as tensions between the two nations reached a boiling point last year amid the conflict with Hamas and Hezbollah - both of which had the backing of Iran. 

Sources told Axios that Sullivan did not advise the president to take action either way but merely presented him with scenarios. 

The report also noted that the National Security Adviser, along with other aides to the president, believed that the degraded nature of Iran's air defenses and missile capabilities and weakened proxy forces could improve the likelihood of a successful strike and decrease the chance of Iranian retaliation. 

Biden reportedly focused on the issue of urgency and whether Iran had taken specific steps to justify a potentially conflict-inducing military strike just weeks before a new administration takes office - though it remains unclear what those steps would include. 

"You can look at the public statements of Iranian officials, which have changed in the last few months as they have been dealt these strategic blows, to raise the question: Do we have to change our doctrine at some point? The fact that that's coming out publicly is something that has to be looked at extremely carefully," Sullivan said during remarks in New York just one week before Christmas Day. 

He also pointed to the blows Iran has seen this year and argued that they could push Iran to develop a nuclear weapon rather than deter it. 

"It generates choices for that adversary that can be quite dangerous, and that's something we have to remain extremely vigilant about as we go forward," Sullivan said.
