Saudi Arabia and the United States have entered a new phase in their relationship following Crown Prince Mohammed bin Salman's recent visit to Washington. The two countries signed a strategic defense agreement and advanced weapons deals, marking the most significant development in their ties since the historic 1945 meeting between King Abdulaziz and President Franklin Roosevelt. The agreements are designed to deter potential threats and foster long-term cooperation, rather than respond to immediate crises. Both nations see each other as essential partners, with the United States providing economic, scientific, and military support, and Saudi Arabia holding strategic importance for Washington. The partnership is expected to endure regardless of changes in American political leadership, reflecting a broad consensus on the value of close ties with Riyadh.
