Despite annual defense expenditures exceeding $82 billion, Saudi Arabia continues to face threats to its critical infrastructure from relatively inexpensive weapons deployed by Houthi forces. These threats primarily target oil facilities and airports within Saudi Arabia, raising questions about the efficacy of the substantial investment in defense. The Houthi’s ability to consistently challenge Saudi Arabia with drones and missiles demonstrates a vulnerability despite the kingdom’s advanced military capabilities. This situation highlights a potential imbalance between costly, high-tech defense systems and the impact of lower-cost, asymmetric warfare tactics. The ongoing challenges underscore the difficulty Saudi Arabia faces in securing its territory and vital economic assets. Further analysis suggests a reassessment of defense strategies may be necessary to address this evolving threat landscape originating from Yemen.
