In a transaction that speaks to the enduring architecture of American power in the Middle East, the United States has authorized a $24.3 billion sale of advanced fighter jets to Saudi Arabia — one of the largest arms exports in recent memory. The State Department's approval deepens a security partnership that has defined Gulf geopolitics for decades, rooted in the exchange of military capability for strategic alignment. As the region's balance of power continues to shift, this deal is less a singular event than a reaffirmation of a long-standing compact between Washington and Riyadh.
