History

Historical Context

The Iran-Iraq War, which began in 1980, significantly impacted the Strait of Hormuz, a crucial maritime route for global oil trade. In 2026, renewed tensions arose following U.S. and Israeli airstrikes on Iran, leading to Iran's threats to block the strait, through which 20% of the world's oil passes. This ongoing conflict underscores the strait's strategic importance and the potential for further military escalation.
