What two operations were among the first successful examples of Multinational Operations?

Operation Desert Shield and Operation Desert Storm are recognized as some of the first successful examples of multinational operations due to the extensive coalition formed to respond to Iraq's invasion of Kuwait in 1990. Over 30 countries participated under a unified command, led by the United States, demonstrating effective collaboration among diverse nations with different military capabilities and strategic interests. This operation set a precedent for future multinational military efforts by revealing the benefits of coordinated actions and shared resources in achieving common objectives.

In contrast, the other operations listed were significant in their own right but did not initially showcase the same level of multinational collaboration as Desert Shield and Desert Storm. While operations like Noble Eagle and Joint Guardian involved international participation, they focused on different contexts or conflicts, and their coalitions were not as expansive or pioneering in nature as that of Desert Shield and Desert Storm.
