Following U.S. strikes on Iranian nuclear sites, Iran’s parliament approved a measure on Sunday to close the Strait of Hormuz, according to state media—a move that, while not yet enacted, heightens geopolitical tensions. The final decision lies with Iran’s national security council. Analysts view actual closure as unlikely, citing high self-inflicted risks for Iran, including alienating neighbors, disrupting its Asian oil markets (especially China), and inviting military retaliation. Experts warn Iran would jeopardize its energy exports and infrastructure. The U.S. is urging China to help prevent escalation.
