Geopolitical analyst Professor Jiang predicts World War 3 has already begun through Iran conflict, revealing how US dollar dominance, energy chokepoints, and competing worldviews between America, Russia, China, and Israel will reshape global order—potentially triggering starvation via Strait of Hormuz blockade. America invaded Iran because allowing Russia-China-Iran alliance would undermine petrodollar hegemony and force the world to abandon US currency for gold-backed alternatives. Iran's mountainous terrain and decentralized military structure (31 provincial armies) make conventional US invasion strategy ineffective, forcing prolonged asymmetric warfare and eventual ground troop deployment. If Russia enters the conflict alongside Iran and China, they could provide financing, reinforcement via Belt and Road railways, and nuclear umbrella protection, forcing America to escalate globally. Blocking the Strait of Hormuz cuts 20% of world energy exports and threatens food security for 89% dependent GCC nations, potentially triggering global starvation and mass refugee crises.
