Sen. Lindsey Graham just called America’s “$1 billion a day” military operations in Iran a great “investment” for America.

During this week’s edition of Fox News’ “Sunday Morning Futures,” host Maria Bartiromo asked the South Carolina senator to justify the staggering cost of the conflict, which the Pentagon is planning to ask for billions more to fund and has sent oil prices soaring.

“Best money ever spent,” he said. “What’s it worth to America to take down a religious Nazi regime who’s trying to build a nuclear weapon to deliver to America? That’s a really good investment.”

Calling it imperative that Iran “never go nuclear,” Graham said, “What would it cost America if Iran had 11 nuclear bombs to threaten us? They would to hold us hostage.”

BARTIROMO: A billion dollars a day. Oil prices up 27% in a week. The president wants a $1.5t defense budget. The Pentagon wants $50b for these strikes.

Iran has long maintained its enriched uranium supply only for its nuclear energy program and research. But a majority of its cache clocks around 60% purity, which experts say is exponentially stronger than what’s needed for civilian use though still shy of 90% weapons-grade levels.

Even if the country realized its nuclear ambitions, its weapons capacity would be minuscule compared to the U.S., which has an estimated 3,700 active nuclear warheads in its military stockpile, according to figures from the Federation of American Scientists released in January 2025.

Graham went on to commend President Donald Trump as a “man of peace and business,” saving the world from “real chaos” as he vowed to vote for his proposed $1.5 trillion 2027 defense budget and a $50 billion supplemental defense package the Pentagon reportedly plans to soon present to Congress.

“Donald Trump is resetting the world in a way nobody could have dreamed of a year ago. Our military is the best of all time,” the senator said. “Iran is going down, and Cuba is next.”
