Go ask ChatGPT which nations are in OPEC. Some (or their regions) are listed (as unstable) in this thread.
They compete with Western Oil interests.
That is why these regions (africa and the middle east) are destabilized, that is that status quo, has been for decades. That's the point, that's normalcy for US hegemony (and western oil interests).
As for the other two issues you raised. Ukraine and Taiwan... Taiwan is never going to happen for a multitude of reasons, that's just saber rattling. Always has been (hence why it hasn't been attempted, even Mao knew it couldn't be done).
Ukraine is serving it's own survival and damaging Putin and the Russian economy in the process - there's no real risk for America there, only a reward.
So all of this is why we have the major wars and current state of the world. Most of it represents "the center holding" as Biden put it. It makes sense if you understand the players and geopolitics.
If they were legally in Israel, as citizens then their bodies were illegally taken and left on mass in a truck in a warzone, that would still be kidnapping.
