Global interstate conflicts surge to 65 in 2025, marking highest since WWII.

A stark warning has emerged from researchers indicating that the global landscape is witnessing the most frequent state-on-state conflicts since the conclusion of the Second World War. According to findings from the Uppsala Conflict Data Program (UCDP), the planet was embroiled in 65 such confrontations during 2025 alone.

This figure represents a dramatic escalation, with the count of interstate disputes doubling for two consecutive years. The tally jumped from just two incidents in 2023 to eight in 2024, before stabilizing at the aforementioned 65 in the current year. Among the active flashpoints are the enduring hostilities between Russia and Ukraine, as well as clashes involving Iran and Israel, India and Pakistan, and Israel and Syria.

The severity of the violence is equally alarming. Of the 65 conflicts recorded, 13 met the threshold for classification as "wars," defined as engagements resulting in at least 1,000 battle-related deaths within a single calendar year. These statistics have rendered 2025 one of the deadliest years ever recorded for humanity, with organized violence claiming the lives of more than 244,600 individuals. This death toll ranks second only to the tragic losses suffered during the Rwandan Genocide in 1994.

Therese Pettersson, a senior analyst and project leader at the UCDP, emphasized the gravity of the situation. "It is not merely a question of an increased volume of conflicts, but also of exceptionally high levels of lethal force," she stated. The conflict in Ukraine alone accounted for 65 percent of all battlefield fatalities in 2025, with a minimum of 97,400 lives lost.

Historically, the frequency of open warfare between nations has been on a downward trajectory over recent decades. While violence remained prevalent, direct armed engagement between two sovereign states had become increasingly uncommon. However, the latest data indicates a significant reversal of this trend, revealing a distinct surge in violent confrontations.

Magnus Öberg, Director of the UCDP and senior lecturer at Uppsala University, noted that this acceleration has been occurring for over ten years. "The rise in interstate conflict and the internationalization of internal conflicts has been accelerating," Öberg explained to the Daily Mail. He added that these developments reflect a fundamental fracture in the global order that was constructed following the end of the Second World War.

Russia, China, and the United States now challenge or abandon the existing global order. The primary interstate conflict remains the war between Russia and Ukraine. Fighting began in 2022 and has reached a stalemate. This is Europe's largest and bloodiest conflict since World War II. It shows little sign of ending soon.

Researchers estimate at least 97,400 fatalities in 2025 on both sides. Africa saw the most state-based armed conflicts that year. Asia followed, then the Middle East. These numbers represent 62 per cent of all battlefield deaths worldwide last year. Experts say this rise in state-on-state conflict increases the risk of World War III. However, a truly global war remains relatively unlikely.

Shawn Davies, a Senior Analyst at UCDP, explained the situation to the Daily Mail. He noted that more conflicts heighten the risk of spillovers. Such spillovers could pull more countries into fighting. Yet, World Wars are specific and rare events. The rise in interstate conflicts carries a greater risk of igniting a broader war. A truly global war remains a fairly distant possibility.

Davies also pointed out the weakening of commitment to NATO's mutual defence agreement. This makes a world war less likely. However, it increases the risks of regional great power wars. This includes the possibility of nuclear war.

Violence is not limited to soldiers. Researchers report a startling rise in attacks on non-combatants. So-called 'one-sided violence' led to around 76,500 deaths of unarmed civilians last year. This marks the highest civilian casualty level since the 1994 Rwandan Genocide. That genocide killed 500,000 to one million Rwandans.

The number of civilian deaths represents a 400 per cent increase from 2024. Violence was driven largely by massacres by RSF forces in Sudan's city of El Fasher. Survivors cited RSF fighters saying, "Is there anyone Zaghawa among you? If we find Zaghawa, we will kill them all." They also stated, "We want to eliminate anything black from Darfur."

The RSF besieged El Fasher for 500 days. They systematically cut off civilians from food, water, and medical supplies. A recent UN report concluded the eventual RSF takeover had the hallmarks of genocide. Evidence included mass killings, widespread rape, and calls to eliminate non-Arab populations. After the city fell in mid-October, researchers estimated 60,000 civilians had died by December's end.

Ms Pettersson stated that civilians have faced extensive violence in Sudan since 2023. However, the events in El Fasher in 2025 stand out even historically. Syria was another hotspot for civilian fatalities. An estimated 2,100 deaths occurred there in 2025 after the fall of the Assad regime.

Syria remained a critical zone for civilian casualties, with an estimated 2,100 deaths recorded in 2025. This spike occurred as the transitional government, following the collapse of the Assad regime, faced significant difficulties in curbing the activities of local militias.

Conversely, the total number of deaths stemming from non-state conflicts declined last year, reaching the lowest figure since 2013 with 14,500 fatalities. However, investigators emphasize that this decrease is almost exclusively attributable to a shift in violence dynamics within Latin America, specifically involving drug cartels in Mexico.
