International defense of Saudi Arabia (1990-91)
After Iraq invaded Kuwait in August 1990, a 35-nation coalition led by the United States deployed hundreds of thousands of troops to Saudi Arabia to deter an Iraqi advance and protect the kingdom.
The coalition expelled Iraqi forces from Kuwait in early 1991.
Set the precedent for foreign troop deployments to defend Saudi territory during regional crises.
The Yanbu deployment is a smaller, more targeted version of the same pattern: external powers sending forces to guard Saudi Arabia when it faces a nearby threat.
