Good analogy, but I would argue that we need to be asking two questions.
Question 1: What caused the fire? It seems like an electrical issue caused the fire, like you pointed out. This is a typically straightforward answer that can usually be pinpointed to a single cause.
Question 2: What caused this fire to be so deadly? That's where everything else that you listed comes into play. A much more complex answer that goes back to an accumulation of decisions and mistakes that built on each other over a period of years.
If we're going to apply that logic to situation in the Middle East, then 10/7 would be the fire that caused everything afterwards up to this point. Everything else was simply existing in the background, just like the people living and hanging out at the Ghost Ship. Without that electrical fault, that fire doesn't start and those people don't die that day. 10/7 was the electrical fault that lit off the invasion of Gaza by Israel. Without 10/7, the other issues are still there, but the situation doesn't ignite in the way that it did.
