is the Saudi still aggressive toward the Yemeni government?
the Chinese government has already made agreed to be peaceful between Saudi and Iran. this will only put them in chaos again and this time, the Saudis are unsure if the US forces will come to the rescue because of the PetroUSD discontinuation. Yemeni blowing up infrastructures means Iran being a Yemeni ally will in against Saudi.

Trump choosing Vance makes no sense but it must confirm being a president or a president to be doesn't mean they are in control. Vance is also a warmonger who thinks China is the real threat and putting the Middle East in chaos means a win for him against China.
