Senator Lindsey Graham of South Carolina died suddenly on Saturday night at the age of 71, according to CBS News. The death of the Republican senator, a towering figure in American foreign policy, removes one of the most influential advocates for a muscular US role abroad, particularly in support of Ukraine and Israel, and leaves a significant void in Washington at a time of global turmoil.

A Sudden End to a Long Career

Lindsey Graham, who represented South Carolina in the House and Senate for more than three decades, died after what a preliminary report from the Washington, D.C., medical examiner's office said was a tear in his aorta, according to PBS NewsHour. The death certificate will remain pending until toxicological and microscopic testing are finalized, The Hill reported. His death came just a day after he returned from Ukraine and four months before he was to face re-election, according to The New York Times.

Graham's Foreign Policy Vision

For decades, Graham traveled the globe selling a vision of the United States as a nation willing to use its military might to protect democracies around the world, even as his party was taken over by a president openly skeptical of that worldview, PBS NewsHour reported. He was a rare bridge between President Donald Trump's "America First" foreign policy and the traditional Washington consensus prioritizing alliances with Europe and Israel, one falling out of favor with many in both political parties. With that idea of the US, Graham remained a staunch defender of Ukraine to the end, even as Trump's commitment wavered.

Graham's global reach was evident in the tributes that poured in from world leaders. Israeli Prime Minister Benjamin Netanyahu called Graham a great friend of Israel and a cherished friend, while Ukraine's President Volodymyr Zelenskyy described him as a true defender of freedom and the values that make the world safer, according to The Guardian. Eulogies also flowed from NATO allies and Taiwan, underscoring that Graham, one of 100 senators in Washington, had a global reach that few could match. He traveled the world to advocate for a muscular US foreign policy, frequently visited American troops stationed overseas, and was vital in shaping Trump's worldview.

However, his legacy was complicated and often bloody, The Guardian noted. Graham was a hardline backer of US-Israeli wars, and his death brought condemnation from Iran and other countries where he had agitated for military action, Al Jazeera reported.

Impact on Ukraine and Iran Policy

Graham's death is a significant blow to Ukraine, which lost its most influential champion inside Trump's mostly "America First" political orbit, according to The New York Times. With Graham gone, advocates for continued US support for Ukraine in its war against Russia lose a key voice who could sway Trump and other Republicans. At the same time, Graham's aggressive stance on Iran—he cheered Trump's approach—means his absence could shift the balance within the Republican Party toward less interventionist policies.

Paul Foldi, a former diplomat and top Republican staffer on the Senate Foreign Relations Committee, was paraphrased by PBS NewsHour as saying that in an increasingly isolationist America, Graham was one of the last titans of the Senate who favored a muscular and engaged US foreign policy, and that he is irreplaceable.

Political Fallout and Succession Questions

Graham's death has immediate political ramifications. Lawmakers from both parties are remembering his life and legacy, but there are new questions about who will replace him in South Carolina, and growing scrutiny about fellow Republican Mitch McConnell's health after a newly released statement and photo of the 84-year-old GOP senator, NBC News reported. The process for filling Graham's seat will be determined by South Carolina law, and the appointment could shift the balance of power in the closely divided Senate.

Reactions from Allies and Adversaries

The international reaction to Graham's death highlighted his polarizing role. While Israeli and Ukrainian leaders praised him, Iran and other adversaries condemned his legacy of advocating for military action, PBS NewsHour reported. The Guardian noted that Itamar Ben-Gvir, Israel's national security minister, was among the first to offer tribute, reflecting Graham's close ties to the Israeli right.
