Described in one media report as bringing the world to the "gates of hell," an Israel versus Iran war would quickly go nuclear, leading to mass death and destruction at an exponential rate.

The destruction of both nations is certain, the simulation shows. And many other surrounding nations, and eventually the rest of the world, would also feel its effects to an unprecedented degree.

The entire Middle East would be reduced to rubble. Then, as the conflict spirals outward from there, entire nations would collapse.

It would start with tit-for-tat missile strikes between the two nations. Then Israel would wage war on Iranian proxies such as Hezbollah and Hamas. Houthis would then fire at ships in the Red Sea, prompting Israel to conduct a nuclear strike. Iran would then respond in kind, igniting full-scale nuclear war.

Israel to fight Iran alone

The simulation was created by both military and security experts who say they know how the conflict would unfold. It contains a step-by-step breakdown of what would transpire and how quickly the whole thing would escalate.

One noteworthy aspect of the war is that Israel would no longer receive help from the United States, having already robbed the nation blind and left it for dead. This leaves Israel to stand alone in a fight against Iran.
