A United Nations-brokered truce in Yemen lasted nearly six months in 2024 before fighting in the country between the Iran-aligned Houthi rebels and the Saudi-backed government started up again in the fall. The Trump administration has recently escalated air strikes against the Houthis in response to their revived efforts to disrupt shipping in the Red Sea.
Donald Trump promised that he would, like some authoritarian father figure, force warring parties in Ukraine, Gaza, and elsewhere to stop fighting and get along. Only the credulous believe in this avatar of Trump as peacemaker.
Last year, a cease-fire in Syria came to an end when rebels, with the go-ahead from Turkey, caught government troops by surprise when they seized Aleppo and kept going. A little more than a week later, they were in control of the capital of Damascus and Syrian dictator Bashar al-Assad was on his way to Moscow.
Cease-fires have come and gone in the Democratic Republic of Congo. Last week, the DRC and Rwanda called for a cease-fire in the eastern part of the country. An astonishing 700,000 people have been displaced by fighting just since January. The record of truces in this war-torn country does not give much hope for this latest initiative.
In other countries, the mutual hostility between the warring parties has been so intense that cease-fires don’t even get a chance to take hold. Sudan, split in two by government forces and the rebel Rapid Support Forces, has so far resisted international calls for immediate humanitarian pauses in the violence.
Cease-fires don’t always fail. Libya hasn’t seen any major violation of the cease-fire signed in 2020. But it’s the only success of the three cease-fires that the Borgen Project cited in October 2022 as evidence of a more peaceful world. The civil war in Sudan resumed in April 2023. Later that year, Azerbaijan broke a cease-fire to defeat Armenia and seize control of the disputed territory of Nagorno-Karabakh.
Donald Trump promised that he would, like some authoritarian father figure, force warring parties in Ukraine, Gaza, and elsewhere to stop fighting and get along. Only the credulous believe in this avatar of Trump as peacemaker. The truth is, cease-fires are usually just empty promises, regardless of how smart, powerful, or delusional the mediator-in-chief happens to be.
What makes some cease-fires endure even as so many others disappear into the fire of renewed hostilities?
Why Cease-Fires Die
When he responded to Trump’s peace proposal for Ukraine, Russian President Vladimir Putin said, “We are in favor of it but there are nuances.”
Those “nuances” were sticking points as sharp as a saber. Putin wants the world to recognize his illegal seizure of four Ukrainian provinces over which he doesn’t even have full control. He wants all foreign military assistance and intelligence sharing with Ukraine to end. NATO membership for Ukraine must be off the table. Oh, and he also wants the world to lift sanctions against his country.
Putin believes that he has an advantage on the battlefield and, with Trump as president, at the negotiating table as well. There is some truth to Putin’s perception. Russia has more soldiers and resources at its disposal than does Ukraine, and Trump is the most pro-Russian president that the United States has ever produced. Putin also knows that the celebrated dealmaker is actually a naïf who pays little attention to details and has been taken to the cleaners in the past, most notably by the Taliban in its 2020 deal with the United States.
But Russia, too, has reached certain limits in its capacity to recruit soldiers and produce the armaments to continue its occupation of Ukraine. Mutual exhaustion is one of the best signs of a cease-fire that can endure. That was certainly the case with the two Koreas in 1953 after two years of relatively little territorial movement by either side.
But both parties to the conflict have to acknowledge, if only to themselves, that they have sunk into a quagmire. Putin, by contrast, thinks that he can prevail. He wants not only those four provinces but the entirety of what he calls “Novorossiya,” which includes all of Ukraine’s southern coast, which would render the country land-locked. Putin also wants elections that can replace Volodymyr Zelenskyy with a more malleable leader.
Any cease-fire that doesn’t lead to Putin achieving these ultimate goals is a cease-fire that Russia is unlikely to uphold.
A power-besotted aggressor who believes that he—and isn’t it always a he?—has an asymmetric advantage over his opponent is one of the leading reasons why it’s difficult to stop wars. Cease-fires for these aggressors are only pauses to regroup or to win international approval or to lull opponents into complacency.
That applies to Benjamin Netanyahu as well. Israel and Hamas have been locked in a conflict over Gaza for more than two decades. On October 7, the much weaker Hamas launched a brutal surprise attack on Israeli territory that killed more than 1,000 people and produced 250 hostages, which the Palestinian group figured it could use as bargaining chips. Instead of negotiating, the Netanyahu government launched its own brutal response, which has left 50,000 dead in Gaza.
Like Putin, Netanyahu has maximalist ambitions and an uncompromising attitude. He wants to destroy Hamas. He also wants to destroy the capacity of Gaza to serve as a part of some future Palestinian state. He doesn’t really care about the hostages that Hamas is holding. The Israeli leader is so determined to prove that Hamas is using Israeli hostages and Palestinian civilians alike as human shields that he’ll sacrifice them both in his bid to annihilate Hamas and, of course, maintain his own political position. To add grievous insult to catastrophic injury, he’ll then accuse the Palestinian group of human rights abuses after the fact.
A huge number of Israelis are fed up. This last weekend, 100,000 turned out to protest in the major cities.
Getting to Peace
Most cease-fires fail, often spectacularly so. “Of the 105 failed cease-fires, 84% were followed by an offensive within an average of just 13 days,” reports Patrick Burke in his study of cease-fires in 25 wars from 1947 to 2016. According to a study by Jason Quinn and Madhav Joshi, 80% of cease-fires fail.
Mutual exhaustion on the battlefield is certainly one factor behind a successful cease-fire. But what can mediators do when one or both sides believe that they can still achieve a complete victory, as Croatia did with Operation Storm in 1995 and Azerbaijan accomplished more recently?
Trump’s approach is to strong-arm the weaker party. He cut off military aid to Ukraine, trash-talked its leader, and forced the country to accept a partial cease-fire. With the latest deal on the Black Sea, he is dangerously close to agreeing to lift some restrictions on Russian exports without approval from Ukraine or the European Union. Such a cease-fire is not likely to last or to lead to a second stage.
Putin is no doubt watching Netanyahu, taking careful notes, and identifying lessons to learn:
- Lesson one: Break previous agreement
- Lesson two: Flatter Trump
- Lesson three: Apply maximum firepower
- Lesson four: Ignore international opinion
From a conflict resolution point of view, a more successful approach would be to identify the underlying reasons for the dispute—competition for resources, historical grudges, cultural differences—and find ways of nudging the parties toward addressing those root causes nonviolently. But this approach assumes a certain power balance among the combatants.
It’s hard to imagine Trump, Netanyahu, or Putin being very interested in such a process. They don’t believe in talk therapy. They believe in power moves.
Where one side has an obvious advantage, an outside force could try to level the playing field. That requires arm-twisting not the weaker party but the stronger one. That’s what the United States did to get Serbia to the table and sign the Dayton Accords to end the war in Bosnia.
Ah, but didn’t the West follow just such a strategy with Russia during the current conflict? All the sanctions against Russia and arms deliveries to Ukraine and resolutions at the U.N. only made Putin fight harder. These punitive actions were taken to help Ukraine repel the invaders and uphold the principles of international law. In other words, the international community has had a stake in the conflict, since Russia didn’t just seize Ukrainian territory, it defied a collective global norm.
With Israel, of course, the Biden administration did little or nothing to restrain Netanyahu. The Trump administration has only encouraged the Israeli leader. Trump’s scenario of a Gaza resort with no Palestinians, however ridiculous it sounds, served notice that the United States would be okay with a genocidal push of all Palestinians from their land.
So, perhaps in some contexts, cease-fires are just bound to fail.
But don’t despair. Remember that 80% failure rate from Jason Quinn and Madhav Joshi? Believe it or not, these researchers were actually encouraged by the results of their analysis of data from 196 conflicts between 1975 to 2011.
“What we found was that the best predictor that any one cease-fire agreement will be successful—and by successful I mean: not followed by renewed conflict or violence—… is how many failed peace agreements came before,” Jason Quinn noted. He pointed to the ultimate successes in ending wars in Nepal and Colombia as important examples.
Wars are hard to end. Exhibit A: The Hundred Years War. It makes sense that cease-fires are bound to fail and fail and fail and fail and fail until one day, they produce a lasting peace. Skilled mediators, a power move or two, mutual exhaustion on the battlefiel and at the negotiating table: These can all eventually lead to success.
But one thing is for sure. Trump’s unholy affection for both Putin and Netanyahu will produce only the worst kind of cease-fire, the kind that the strong use as a prelude to their final push to eliminate the weak.
