Wasn't sure since you'd only listed Gaza and West Bank as some people have the thought that Hamas (in Gaza's case) were being taken care of by...Hamas. Thanks for the clarification but that's the reality too. Israel gave them everything. To your point, this is because you'll not find a nation or even a business which is Jewish operated which is in shambles the way you do with the islamic trash. I tried posting it yesterday but as many now know, IDF (Israel) vacated the Al-Shifa hospital and brought in 1st world medical care before entering in. It's documented and what did Hamas do for those in the hospital? How many was Hamas paying for electricity, supplies, etc? Nothing. The people were their human shields and that's where you'll find life expectancy drops. By the way, check out that link because most won't even believe Iran looked like that.
FYI -- have a friend whose parents were born in pre-Islamic revolution Iran. They're not Muslim and the destruction of their civility lead them to taking their wealth to the U.S.
