History

Historical Context

After Iraq’s August 1990 invasion of Kuwait threatened Saudi oil fields, the United States deployed forces under Operation Desert Shield and launched Desert Storm in January 1991, leading a 42-nation coalition that flew over 100,000 sorties and cost the U.S. about $61 billion. The 2026 Iran conflict has prompted a similar $87.6 billion Pentagon request, showing how large-scale wars repeatedly pressure U.S. budgeting.
