Iran war threatens global food and chip supplies through Strait of Hormuz control, warns economist who predicted 2008 crash. Professor Steve Keen explains how 20% of world's fertilizer and helium pass through one 21km gap, putting 8 billion people at risk of famine within months if conflict escalates. Iran has decentralized its military into 31 independent provincial commands with buried weapons systems, making traditional decapitation strategy impossible and forcing opponents toward nuclear escalation. Twenty to thirty percent of global fertilizer, helium, and liquefied natural gas transit the Strait of Hormuz; losing this supply would eliminate 20% of world food production and collapse semiconductor manufacturing within months.
