The background of the repeated changes in attitude towards

The background of the repeated changes in attitude towards Saudi Arabia (2018-2022): The United States has long regarded Saudi Arabia as a strategic pillar in the Middle East, but the murder of Khashoggi has triggered public pressure. Betrayal: Biden promised to turn Saudi Arabia into a "pariah state" during his campaign, but in 2022 he took the initiative to visit Saudi Arabia to increase production in order to lower oil prices. The United States acquiesced to Saudi Arabia's involvement in the Yemeni civil war, but suspended some arms sales on the grounds of "human rights" (later resumed). Consequences: Saudi Arabia accelerated its move towards China and Russia, promoting oil-yuan settlement; the moral authority of the United States was further damaged. Deep-level model analysis

1. Contract instrumentalization: The United States regards international agreements as "temporary contracts" that can be torn up at any time due to domestic political or strategic interests (such as the Paris Agreement and the Intermediate-Range Missile Treaty).

2. Ally hierarchy: Core allies (Five Eyes Alliance): priority maintenance; secondary allies (Japan, South Korea, NATO): conditional use; instrumental allies (Kurds, South Vietnam): use and discard.

3. Discourse control: "betrayal" is packaged as "strategic adjustment" or "democratic mission" through the media and NGOs.
