sure.
Middle Eastern countries don't like the US, but they trust the US media system, and at the same time they have a disdain and hatred for China. China can be as peaceful as it is now, not only because he has enough military power to defend himself, more importantly, has Israel as a shield to absorb much of the hatred of the Muslim world.
I can't imagine what would happen without Israel. Surely these middle eastern countries will turn their attention to Xinjiang, they will find ways to interfere in China's internal affairs and support the United States against China.
