The Republican presidential candidates have shifted their focus from threatening Mexico to saber-rattling against Iran. Sen. Tim Scott took the most aggressive stance, advocating for direct American airstrikes on Iranian military units to stop recent strikes against U.S. forces in Iraq and Syria. Other candidates, with the exception of businessman Vivek Ramaswamy, were asked if they would support military action against Iran. Former South Carolina Gov. Nikki Haley came close to supporting strikes, while former New Jersey Gov. Chris Christie mentioned isolating Iran internationally. However, the candidates did not address the question of why American troops are in Iraq and Syria in the first place. Florida Gov. Ron DeSantis also expressed mixed views. The leading candidate, Donald Trump, was not part of the debate. While in office, his foreign policy toward Iran was marked by caution. Other candidates should remember that Republican primary voters favor foreign policy restraint, not new foreign wars.
