Gov. Ron DeSantis of Florida is widely considered the strongest potential primary challenger to former President Donald Trump’s third campaign in 2024. His national profile, developed during the Covid-19 pandemic and in battles over public education, is by definition domestic, and yet his experience as governor is an obvious precursor to the highest office. Especially if Mr. DeSantis runs in 2024, there is the real possibility that he will emerge as the new leader of the G.O.P.
But there’s one major presidential responsibility in which governors’ records are often lacking, or at least little-known: foreign policy. Were he elected president, Mr. DeSantis would become America’s top diplomat, commander in chief and maybe the Republican Party’s direction-setter on foreign policy for years to come in Ukraine, Taiwan, Iran and beyond.
How a prospective Republican presidential candidate views foreign policy feels like a question from a different era. For several years, the party’s politics and understanding of its role at home and abroad have revolved first and foremost around Mr. Trump. But in the years since Mr. Trump became president, the G.O.P. coalition has split over America’s role in the world, the causes and conflicts which deserve U.S. intervention and the value of international alliances.
