KSA the sitting duck won't sit there for long. It will retaliate. The attack yesterday cut its throat, and KSA gov has acknowledged its oil production is down to half. Global supply chain down 5%. And USA is ready to tap its strategic reserve.
In case this escalates, which is a high possibility, USA and Israel won't have to run the show. They can just sit back and watch war break out between KSA and Iran.
Keep watching. Situation changing every week so drastically that it's like chaos.
