Answer: A. It was a successful military operation.
Explanation: The 1990-1991 Gulf War, also known as Operation Desert Storm, was a successful military operation led by a coalition of forces from 34 countries, primarily the United States, against Iraq. The war was prompted by Iraq's invasion of Kuwait in August 1990 and aimed to expel Iraqi forces from Kuwait and restore its sovereignty.
The war was successful in achieving its objectives, with Iraqi forces being driven out of Kuwait and the country's military capabilities being significantly weakened. The coalition forces achieved air superiority early on in the conflict, which allowed them to launch a ground offensive that quickly overwhelmed Iraqi forces. The war also demonstrated the effectiveness of new military technologies, such as precision-guided munitions and stealth aircraft.
However, while the military operation was successful, it did not fully resolve the regional conflicts that had prompted Iraq's aggression, and tensions in the region have persisted in the years since the war. The war was also not waged entirely by U.S. military forces, as it was a multinational effort with significant contributions from other countries. While the war did impose a financial burden on the United States, it did not create a fiscal crisis.
