Well, the dam that killed those people was built to prevent flooding, and help with water for irrigation. It's was a neccessary preventive structure to avoid people dying in the first place - that failed after 15 years of lack of government, civil war, and related non-maintenance. Not something they've built despite having other options. At least it wasn't a nuclear factory that could fall into the hands of ISIS (also operating there), and whose materials could be used for bringing havoc all over the globe.
