Santos, who received the Nobel Peace Prize in 2016 for his efforts to end a five-decades-long civil war with a guerrilla group that killed more than 200,000 people in the South American country, served as president of Colombia from 2010 to 2018.

Known as a tenacious negotiator, Santos said, “The big challenge in the 140 conflicts currently in the world is that leaders need to sit down and talk in very constructive ways.”

Titled “The Power of Long-View Leadership,” the event included opening remarks from Alberto Díaz-Cayeros, senior fellow at the Freeman Spogli Institute for International Studies (FSI), as well as a brief response followed by an audience Q&A moderated by Héctor Hoyos, director of the Center for Latin American Studies.

Díaz-Cayeros said, “This discussion is especially timely and vital today as we confront global challenges – not only here in the United States but throughout the hemisphere and around the world – that demand both moral courage and a strategic vision.”

Listening, talking

In November 2024, Santos was appointed Chair of The Elders, the organization founded by Nelson Mandela to advocate for peace, justice, human rights, and a sustainable planet.

In his address, Santos explained the process of bringing the guerrilla group – the Revolutionary Armed Forces of Colombia, or “FARC” — to the peace negotiating table. A meeting in the late 1990s with Mandela, the South African anti-apartheid activist, was particularly inspirational.

“He taught me why that program (in South Africa) to bring victims and perpetrators together to reconcile for the future was so important,” said Santos, who described it as the most interesting conversation he’s ever had about peacemaking.

So, he started studying peace processes all around the world — the ones that were successful, the ones that failed, and the ones that still held out hope. Gradually, he identified the conditions that were necessary to begin an authentic peace process with the FARC.

“What had my predecessors done wrong? What could I bring from other examples around the world?” He came to understand that three key conditions existed in the Colombian dynamic.

“As long as the guerrillas think that they will win through violence,” Santos said, “they will never sit down in good faith. They have to be convinced that they will never achieve power through violence. Second, the leaders of the guerrillas themselves personally have to be involved in the negotiations.”

Finally, he said, Colombia’s neighbors needed to support the peace process, or the guerrillas would always use those neighbors as safeguards and not commit to the peace process.

Santos brought on advisors who had successfully negotiated peace deals in other global hotspots. Some of the advice was especially sage.

“I was told to treat the FARC not as our enemies but as our adversaries. Enemies you eliminate. Adversaries you beat.” So, he instructed his military to make policy changes and to be conscious of all their actions, which they would live with forever.

“Treat them (FARC members) as human beings,” Santos said. “They have mothers, they have fathers, so while you fight with them, understand that they're human beings. So, I changed the whole military doctrine.”

A 2016 national referendum in Colombia rejected the peace deal by a narrow margin. Since then, the government and FARC have largely upheld the ceasefire and called for a broader national dialogue to continue the peace process.

Today, Santos is concerned that the gains from Colombia’s peace agreement with the FARC are unraveling. “The difficult path in every peace process is how to reconcile in order to have peace in the long run.”
 

Humanity’s clock ticks

In January, Santos was invited to deliver an address at the annual unveiling of the Doomsday Clock’s time, which is set by the Bulletin of the Atomic Scientists. He noted that the only criteria that existed through the 1990s was the possibility of nuclear war. Now, existential threats to humanity’s fate have rapidly expanded, including climate change, AI, pandemics, and biological threats.

At 89 seconds to midnight, the Doomsday Clock stands closer to catastrophe than at any moment in its 77-year history, Santos said. The clock speaks to the threats that confound and confront us — and the need for cooperation, unity, and bold leadership to turn back its hands.

Unfortunately, what is happening around the world reflects the contrary, Santos said. The multilateral system, the respect for the rule of law, and the respect for protocols are all under attack.

Long-term leadership that makes decisions — not according to the next election, but according to the well-being of future generations — is what the world truly needs, Santos noted.

“How can we do what we did in Colombia on the world stage? That is the great challenge, and that’s when dialogue is imperative,” he said.
 

Instead of competing amongst each other to see who wins this or who wins that, Santos urged that “world leaders need to sit down and talk about how to work together to avoid nuclear war, control climate change, regulate AI, and more.”

“Every second counts,” he concluded.

Student and community engagement

Following the lecture, Professor Héctor Hoyos praised Santos for his unwavering commitment to education, both as President and throughout his career. Reflecting on a personal experience, Hoyos shared a formative moment from his own childhood, when he received a letter from then-Secretary of Education Santos, recognizing him as one of Colombia's most promising young students. "I want to thank you publicly for that gesture, which went a long way," Hoyos said of the experience that inspired him to pursue the scholarly path he follows today.

The lecture also sparked lively engagement among students, many of whom lined up to ask thoughtful questions about applying Santos’ insights to current global challenges. Their inquiries reflected a desire to connect lessons from Colombia’s peace process to diverse contexts around the world. Santos, practicing the very principles of dialogue he had emphasized, listened attentively, responded thoughtfully, and demonstrated a genuine willingness to engage in a constructive exchange of ideas.

After the event, Santos joined more than twenty students from the Graduate School of Business and other programs for a lunch, where discussions continued on leadership, peacebuilding, and the importance of dialogue in addressing contemporary issues.

Kathryn Stoner, the Mosbacher Director of the Center on Democracy, Development and the Rule of Law (CDDRL), introduced the panelists, and Michael McFaul, director of the Freeman Spogli Institute for International Studies (FSI) and a former U.S. ambassador to Russia, moderated the discussion.

On the frontlines, outnumbered Ukrainian troops have waged a stiff resistance, while a mass influx of Russian troops, with enormous loss of life, have made incremental but not decisive progress. Hundreds of thousands have died or been injured on both sides. Talks to end the war are underway between the Trump Administration and Russia, with Ukraine and European nations not currently invited to participate.

‘We will cease to exist’

Matviichuk, who was a visiting scholar from 2017-2018 with the Ukrainian Emerging Leaders Program at CDDRL, noted the conflict has actually been going on for 11 years, since 2014 when Russia invaded and occupied Crimea. Today, she said, there is no safe place in Ukraine where people can hide from Russian rockets. “Just two days ago, Russia sent 263 drones against Kyiv and other peaceful cities in Ukraine.”

Matviichuk described how Russia seeks to ban the Ukrainian language and culture, and how they take Ukrainian children to Russia to put them in Russian education camps. “They told them they are not Ukrainian children, but they are Russian children.”

If the West does not provide Ukraine with security guarantees in a peace plan, then “it means that we will cease to exist. There will be no more of our people,” Matviichuk said.

Oleksandra Ustinova, a member of the Verkhovna Rada, Ukraine's Parliament, said, “If we talk about life in Ukraine now, it's complicated, especially during the last week after the Munich Security Conference,” where Vice President JD Vance delivered a speech that focused on internal politics in Europe.

“People do not understand how we thought the United States was our biggest partner,” she said.
 

At one point, Ustinova noted that she could not hear the conversation in her headphones because sirens were blaring as Russia had just launched an aerial attack on Kyiv.

She said that Russian President Putin and others who seek a Ukrainian election are trying to set a trap because Ukrainian law does not allow an election during martial law, which Ukraine has declared because of the Russian invasion. Plus, it would involve the demobilization of more than 400,000 troops.

“It would be very easy to fake elections, and that’s what the Russians would do,” Ustinova said. “It’s a trap. They're going to find where to put the money into their own candidate.”

Ustinova, who was also a visiting scholar with the Ukrainian Emerging Leaders Program from 2018-2019, said, “We can see that this is a new reality, not only in the Ukrainian war, but in foreign relations, and hopefully the Europeans can unite. Because if they don't, it will be a disaster for everyone.”

Oleksiy Honcharuk, a former Ukrainian prime minister from 2019-2020 who was the Bernard and Susan Liautaud Visiting Fellow at FSI in 2021, said, “I think that we are still strong. My prediction is that in three or six months, Ukraine can double the damage to Russia on the battlefield from a technological perspective with drones.”

But time is very expensive now, he added, because every single day, every single hour, Ukrainians are paying with the lives of their best people and soldiers.

Honcharuk said Ukrainians are “shocked” about the position of the United States’ recent vote against a United Nations resolution condemning the Russian invasion as well as the Trump Administration’s position on talks with Russia.

“This is exactly the moment when all the people of goodwill should do everything possible to support Ukraine in this very complicated time,” said Honcharuk.

Regarding the UN vote, McFaul said, “I am shocked, I am appalled, I am embarrassed as an American to see those votes today. We are voting with the most horrific dictators in the world.”

‘Not about people’

Matviichuk said, “Putin started this war of aggression, not because he wanted to occupy just more Ukrainian land. Putin started this war of aggression because he wanted to occupy and destroy the whole of Ukraine and even go further. He wants to forcibly restore the Russian Empire — he dreams about his legacy, his logic is historical.”

This ultimately means that Ukraine needs real security guarantees, she said. “President Trump said he started the peace negotiation because he cares about people dying in this war. So, if President Trump cares about people dying in this war, he also has to care about people dying in Russian prisons.”

She explained that she’s spoken with hundreds of people who have survived brutal conditions in Russian captivity. And so, it’s surprising, Matviichuk said, to hear political statements from U.S. officials “about natural minerals and elections, about possible territorial concessions, but not about people.”

Lack of Global Support

Serhiy Leshchenko, an advisor to Ukrainian President Zelenskyy’s Chief of Staff, spoke about the recent overtures by the Trump Administration to Russia.

“This is a new reality we are living in now. Frankly, my understanding is that Ukrainians are not very shocked with what's going on because we went through so many shocks within the last three years.”

Acknowledging the lack of an American flag at an allied event this week in Kyiv, Leshchenko said Ukrainians know perfectly well that perception is reality.

“It means that now we have an absolutely different perception. So, it’s obvious that there is no global security infrastructure anymore. It’s obvious that NATO is not an answer anymore,” said Leshchenko, an alumnus of the 2013 cohort of CDDRL’s Fisher Family Summer Fellows Program.

‘Sad occasion’

In her opening remarks, Stoner noted, “We’re here on what is actually a sad occasion, which is that Feb. 24 marks three years since the start of the full-scale Russian invasion of Ukraine.”

She said, “Only about less than 1% of land has changed hands since December 2022, so Ukraine is not losing. Ukraine is at least defending what it has, and it remains in Kursk (Russia).”

McFaul said, “It’s in our national interest that we do not line up with Belarus and Russia and North Korea – that holds negative consequences for our future security and prosperity. I actually think our country cares about values.”

He added that the notion that all America cares about is mineral rights, business deals, and hotels in Gaza is not the America he knows.

McFaul told the panelists, “I've witnessed and observed what you’ve been doing for your country, and we are just extremely fortunate to be connected to all of you, whom I consider to be heroic individuals in the world.”
