On Thursday, CNN correspondent Sam Kiley suggested that a U.S. military strike on Iran would result in a major war that no one could win. I support President Trump’s effort to avoid a conflict, but I disagree with Kiley’s assessment.

For a start, there’s little reason to think that a limited U.S. military strike against Iran would result in a far broader conflict. The same is true of limited Saudi retaliation for Iran’s recent attack on Saudi oil facilities.
