The relationship between Saudi Arabia and the United States is a complex and long-standing strategic partnership, primarily built on energy cooperation and security interests. The US relies on Saudi Arabia, one of the world's largest oil producers, to help stabilize global energy markets, while Saudi Arabia depends on the US for military support and defense against regional threats. However, the relationship has faced challenges and criticism over human rights concerns, the Saudi-led intervention in Yemen, and the investigation into the murder of journalist Jamal Khashoggi, leading to periodic strains and debates about the future of the alliance.
