Two senior Republican senators say the United States, and not Israel, should attack Iran if military action becomes "necessary."

They also say a simple strike at the country's nuclear capability wouldn't be enough -- the US would have to launch an "all-or-nothing" war against Iran with the aim of crippling the country's military capabilities.

"I think an Israeli attack on Iran is a nightmare for the world, because it will rally the Arab world around Iran and they're not aligned now. It's too much pressure to put on Israel," Sen. Lindsey Graham (R-SC) told Fox News' Chris Wallace.

He continued: "If the sanctions fail, and Iran's going down the road to get a nuclear weapon, any Sunni Arab state that could, would want a nuclear weapon. Israel will be more imperiled. The world will change dramatically for the worst. Military action should be the last resort anyone looks at, and I would rather our allies and us take military action if it's necessary."

But Graham doesn't think an attack should be limited to airstrikes on Iran's nuclear facilities. "If we use military action against Iran, we should not only go after their nuclear facilities. We should destroy their ability to make conventional war. They should have no planes that can fly and no ships that can float," said Graham.
