History

Historical Context

The Iran-Iraq War, which began in 1980, significantly disrupted global oil supply routes, particularly through the Strait of Hormuz, a vital passage for 20% of the world's oil. Recent refusals by Australia and Japan to support U.S. naval efforts reflect ongoing geopolitical tensions.
