Less dependency on foreign oil is good for peace since the US will not be "protecting their interests". And Saudi Arabia having less budget for their wars is also a good thing.
In the meantime, China is building a global supply chain to provide with world with solar panels and batteries. And bankrupt all the US companies/banks that keep investing in fossil fuels. It's all about your investment horizon I guess.
If the US stays focussed on mid-east for the next 2 decades, and not counter China. Or rather just let China be as they are. China will have the world domination on a platter for the next few centuries.
Oil is the old game. That game probably even ended after the 1990's. The US has been fighting wrong wars for the past 30 years.
China is quietly, and yet steadily emerging as the next super power. Albeit like the UK in the past. No intention to fight any direct wars or make aggressive moves. Instead control the world's oceans, and establish trade empires. Let the current super power bankrupt itself fighting wars.
