Republican Senator Lindsey Graham has urged Donald Trump to “go all in” and attack Iran’s Fordow nuclear site, which is dug deep into a mountain in central Iran.

“Israel dominates the skies and has destroyed Iran’s military and scientific leadership. They have also done great damage to Iran’s nuclear infrastructure,” he wrote on X.

“However, the one site left standing — the deep underground Fordow site — must be dealt with to achieve the common objective of making sure Iran’s nuclear enrichment programme ends,” the senator added.

He stressed: “The capabilities possessed by the United States for such a deep underground attack are unique to us and us alone. Overwhelmingly, Americans view the Iran nuclear threat as existential to both the US and Israel.”

“Go all in. Finish the job.”
