The idea of a third world war has loomed over global affairs for decades. Right from the days of the Cold War, this speculation has been in the air, given the memories of the First two World Wars were fresh. Berlin, October 27, 1961. Under the cold glare of searchlights, American and Soviet tanks faced each other at Checkpoint Charlie, engines rumbling, barrels locked in a silent, deadly stare. A single misstep could ignite World War III. Soldiers stood tense, fingers hovering over triggers, as diplomats scrambled behind the scenes. For sixteen agonising hours, the world held its breath. Then, one by one, the tanks withdrew—first the Soviets, then the Americans. The crisis had passed, but the message was clear: in a divided Berlin, the Cold War’s front line was a hair-trigger away from catastrophe.
Among other such incidents was also October 27, 1962, when the world teetered on the brink of annihilation. Deep beneath the ocean, a Soviet submarine, B-59, lurked in the Caribbean, hunted by U.S. warships. Depth charges exploded around it, shaking the crew in the sweltering, oxygen-starved confines. Believing war had already begun, the captain prepared to launch a nuclear torpedo. Two officers agreed. One man did not. Vasili Arkhipov, the lone dissenting voice, refused to authorise the strike. His defiance averted catastrophe. As the submarine surfaced, the crisis de-escalated, and humanity unknowingly escaped its closest brush with nuclear doom, saved by a single, steadfast decision.
Even now, whether it is the Russia-Ukraine conflict or the involvement of almost the whole Middle East, in the Israel-Palestine strife, the world holds it breath in anticipation of WWIII, given the involvement of Western powers.
But what would it actually look like if it began today? In an era defined by hypersonic missiles, artificial intelligence, cyber warfare, and nuclear brinkmanship, the first 24 hours would not resemble past conflicts. Instead, it would be a highly complex, multi-theatre event where decision-making speed will matter more than sheer firepower.
Hour 1: The Flashpoint
There are many tensions brewing across the world which could erupt into mutually assured destruction (MAD). Although diplomats are working day and night to avoid escalation at all costs, all it would require is one misstep. One trigger, and it would be a slippery slope from there.
In this speculative scenario, the war begins with a sudden and decisive act of aggression. This could take multiple forms:
- Taiwan Strait – China launches an all-out invasion of Taiwan, with missile strikes and naval blockades.
- Eastern Europe – Russia crosses into NATO territory, attacking the Baltics or expanding its push into Ukraine.
- Middle East – Iran launches missiles at Israel, triggering immediate retaliation.
Air raid sirens blare. Military command centres in Washington, Moscow, and Beijing go into full crisis mode. Governments scramble to assess the situation.
Hour 2: Global Military Mobilisation
As tensions spiral out of control, the world braces for impact. The United States, Russia, and China have placed their nuclear forces on high alert, signalling a level of threat not seen in decades. NATO has initiated rapid military deployments across Europe, while key Indo-Pacific nations, India, Japan, and Australia, rush to implement emergency defence measures. Global markets have reacted sharply, with stock exchanges in freefall as fears of escalation ripple across continents. In cities close to potential flashpoints, the atmosphere has turned electric with fear. Civilians are beginning to flee en masse, crowding highways, train stations, and airports in search of safety. The spectre of global war no longer feels distant, it’s unfolding in real time, and the world is watching with bated breath.
Hour 3: Missile Strikes Begin
Long-range missile systems go into action:
- China fires DF-17 hypersonic missiles at US bases in Japan and Guam.
- Russia launches Iskander missiles at NATO positions in Poland.

Hour 7: Special Forces Deploy
- US, Russian, and Chinese special forces conduct high-risk operations behind enemy lines.
- Covert missions target military leadership, radar stations, and supply depots.
- In Taiwan and Ukraine, elite units sabotage enemy infrastructure.
- These operations are crucial in disrupting enemy logistics and command structures.
Hour 8: Civilian Panic and Mass Refugee Movements
As the crisis deepens, panic takes hold of cities across Europe and Asia. Millions are desperately trying to escape, overwhelming transport networks and triggering chaotic scenes at borders. In response to the growing unrest, several governments have declared martial law, hoping to maintain some semblance of control. But with global supply chains in disarray, essential goods like food and fuel are vanishing from shelves. Long queues, empty supermarkets, and soaring prices have become the new normal. The strain is beginning to fracture social order, protests erupt, law enforcement struggles to cope, and in some regions, basic governance teeters on the edge of collapse. What began as a geopolitical standoff is now a full-blown humanitarian catastrophe, with no clear end in sight.
Hour 9: First Major Ground Invasions Begin
