> When the US, the west etc. cuts ties then the KSAs of the world get driven to the arms of Russia and China and other people who will happily do business with them no matter how many journalists they dice up.
This political opinion must be subject to the most severe censure, as is the moral character of people who can come with such an idea.
FISRT, it's untrue, and dishonest.
The world is already driven by Russia's and China's protection racket no matter how many journalists America's rogue state allies dice up.
Adherence, or non-adherence to American military aid makes ZERO DIFFERENCE to that. In fact, there are now more receivers of American military aid in Chinese, and Russian pocket than ones who aren't. In other words, the net effect of US military aid is the benefit of allies, and satellites of Russia, and China. This makes no sense.
SECOND, you lose allies by supporting rogue regimes for reasons ethical, or not.
Saudis are a piece of red cloth to every moderately sane regimes, and states in the region. They know Saudis are an intrusive force which does not stop at staging palace coups, and activity by secret agents to keep the whole Arab world under a thumb. Saudis tried to staged coups, and send clandestine agents to topple both democratic, or not governments of pretty much every Arab country.
THIRD, USA is not impotent at all to influence KSA. USA is fully capable of erasing KSA regime with a flick of a finger with both military, and non-military options on the table.
1/3 of KSA population will raise in arms the second it's given such opportunity. Economic sanctions on oil, and foreign assets will nuke KSA treasury, and lead to regime fall in at maximum of 2 years. USA military contingent in military bases on KSA soil is big enough to topple the KSA military in days.
FOURTH, the new Saudi establishment will be naturally more receptive to US influence than the current one which sploshes moneys on states which are not by an inch friendly to USA. Cutting Saudi moneys to rouge states will instantly solve at least halve of USA's headaches in the region.
