Final answer:
The top financial contributors to the Persian Gulf War were the United States, Saudi Arabia, and Japan, who supported the international coalition led by the U.S. to liberate Kuwait from Iraqi occupation.
Step-by-step explanation:
Top Contributors to the Persian Gulf War Costs
The Persian Gulf War in 1991 was a significant conflict triggered by Iraq's invasion of Kuwait. The top financial contributors to the cost of the Persian Gulf War were the United States, Saudi Arabia, and Japan. These nations provided substantial financial support for the military operations against Iraq. An international coalition led by the United States, which included the United Kingdom, France, Germany, and a plethora of other countries, participated in Operation Desert Storm to liberate Kuwait.
In terms of support, the United States shouldered a significant portion of the military expenses, both in terms of direct military action and by supporting allies. Saudi Arabia, being geographically close and threatened by Iraq's aggression, had vested interests in contributing to the coalition forces. Similarly, Japan, while not contributing military forces due to its pacifist constitution, offered substantial financial backing to support the United States-led coalition.
The success of the operation can also be attributed to the international coalition that included NATO members and other nations that recognized the threat posed by Saddam Hussein's ambition to control the oil-rich region.
