The main problem we are witnessing in the Middle East is overpopulation

When there is no social welfare system present and young men and women can't get married under 35 or 40 years of age in countries where you don't date because they are Muslim where you ONLY marry, you are going to see some of the problems we presently see in the Middle East.

At first, these inequalities created Arab Spring but then Iran, Assad, and Russia resisted Arab Spring in Syria and that created ISIS.

But still, the initial cause was overpopulation, not enough water or food grow to support all people in areas and not being able to get married because there were no jobs for people under 35 years old. In most middle eastern countries 50% or 60% of young people under 35 cannot get work so they cannot marry ever.

This created the basic problems we are facing now in the middle east.

When you have no birth control (because it isn't allowed) and then you don't have enough water or tillable land and then people can't get jobs or get married in Muslim countries you can begin to see why problems the last 20 years or so began to arise.

And now, we see populations being decimated either directly by war or indirectly by starvation or mayhem or both, and this is what we all are actually witnessing every day on the news.

And so, this could spread through almost every Muslim nation in the middle East because the problems there are not being solved by anyone.

In the end the only permanent solution would be birth control so people don't have more children than the deserts allow to survive there.

However, with desalinated water this might change things too like they have in Saudi Arabia and Israel. But, that cannot happen with millions dying in wars like right now.

Note:
I'm thinking that if you actually tallied up all the people have died from Arab Spring and the civil wars in Syria, IRaq, Egypt, Yemen etc. in the Middle East you likely would have a figure now over 1 million people dead from the chaos that is spreading in the middle east right now. And also, there doesn't seem anything that can stop this suicidal movement called ISIS (at least not just yet).

And just like Iran leaders said paraphrased, "ISIS will tend to destroy not only all Shia governments but also all Sunni Governments as well except ISIS' own government." I think this is true of ISIS if left unchecked across the middle east.

So, 10 to 20 years from now, Saudi Arabia and Iran might be gone as governments if this is true.(which should be scary for all Sunni governments as well as Shia governments across the middle East.

And what would that do to the poorest countries on earth without a good price for Saudi or Iranian oil? (or no oil at all coming from either place because of a war between them directly?)
