The Foundation for Peace Professionals (PeacePro) has warned that a third World war could result in more than 500 million deaths.
PeacePro backed up its claim with historical escalation patterns in warfare and the unprecedented destructive capacity of modern nuclear weapons.
These were contained in a statement by Abdulrazaq O Hamzat, Executive Director, PeacePro, in which the organisation warned the escalation of tensions in the Middle East following ongoing military confrontation involving the United States/Israel and Iran, could expand into a wider regional or global crisis.
The organisation in a new strategic report titled; “Global Escalation of Warfare and Projected Human Cost of a Potential World War III,” authorized by Hamzat, noted that modern history shows a clear pattern of rising casualties in successive global wars.
Hamzat particularly noted that the World War I, fought between 1914 and 1918, resulted in approximately 10–20 million deaths, adding that 21 years later, the world descended into World War II, which lasted from 1939 to 1945 and claimed an estimated 50–70 million lives, representing a 400–500 percent increase in casualties.
PeacePro emphasised that this dramatic escalation was largely driven by advances in military technology and the expansion of warfare to civilian populations.
According to Hamzat; “The lesson from history is that each major global war has been far more destructive than the one before it”.
The PeacePro report further stated that modern warfare has entered a fundamentally different era due to the development of nuclear weapons, saying that the atomic bombs dropped in 1945 had explosive yields of about 15 kilotons.
It also said; “Yet, modern nuclear warheads are significantly more powerful, often ranging from hundreds of kilotons to several megatons”.
PeacePro highlighted that the most powerful nuclear device ever tested, the Soviet Tsar Bomba, had a yield of about 50 megatons, making it more than 3,000 times stronger than the Hiroshima bomb.
It further said that modern missile systems are capable of carrying multiple nuclear warheads, enabling a single missile to strike several cities simultaneously, thus warned that these technological advances mean a large scale nuclear exchange could devastate entire regions within minutes.
PeacePro’s warning comes as the conflict involving the United States/Israel and Iran continues to intensify with a war that
involved airstrikes, missile attacks, and drone operations across multiple locations in the Middle East, thereby raising fears that additional regional actors could be drawn into the conflict.
This was as analysts warned that if the war expands, particularly if major powers become directly involved, it could significantly increase the risk of a broader international confrontation.
PeacePro also said that the conflict threatens critical global energy infrastructure and strategic shipping routes such as the Strait of Hormuz, through which roughly one fifth of the world’s oil supply passes, stressing that disruption in this corridor could trigger severe economic consequences worldwide and further destabilize global security.
PeacePro estimates that if a global war were to occur in the nuclear age, the human cost could reach more than 500 million deaths.
The organization said casualties would likely arise from multiple sources, including direct military strikes on cities and infrastructure, nuclear detonations and radiation exposure, collapse of global food and energy supply systems, economic and financial system breakdown and mass displacement and humanitarian crises etc.
It further said; “In addition to immediate casualties, scientists notes that large scale nuclear warfare could trigger nuclear winter, a scenario in which massive amounts of smoke and debris block sunlight, potentially devastating global agriculture”.
PeacePro therefore urged global leaders to prioritize diplomacy and international cooperation to prevent escalation, just as it called for renewed efforts to strengthen nuclear arms control agreements, expand diplomatic engagement, and reduce geopolitical tensions between major powers.
“Humanity has already witnessed the devastation of two world wars. But in the nuclear age, a third global war would not simply be another conflict between nations, it could become a civilization level catastrophe,” Hamzat said.
PeacePro suggested that preventing a global war must remain one of the highest priorities of the international community, warning that failure to do so could result in the largest human tragedy in recorded history.
