But the drought was not caused by climate change, but by mismanagement ie complete neglect of the problem.

I recall reading about a paper in SciAm or American Scientist a couple of decades ago, where they had trained a ML model to predict regional conflicts or civil wars. The main input was scarcity of food, mainly through price IIRC.

They trained it on historical data up to the 90s or so, and had it predict the "future" up to the time of the article. And as I recall it did very well. They even included some actual near-future predictions as well which also turned out pretty accurately as I recall.

Which I suppose isn't a huge surprise after all. People don't like to starve.

while the drought was the last straw, i think the mismanagement of their water resources by the regime (for embezzlement of public funds, direct or indirect, into insider pockets etc) is the true root cause. There's "enough" water to last thru the current drought, if it was better utilized in the past.

That, plus decades of mismanagement and corruption...
