“Don’t be surprised if the Iranians take Mosul by flooding it.”
Downriver from Mosul on the Tigris are Baghdad and Basra, which are major assets of the Shia.
Except for the Kurdish area in the North, the Iraqi population is clustered along the two great rivers. The great bulk of the Arab population lives within walking distance of one of the rivers. Unlike most Arab Cuisine, a big roast river fish is a typical Iraqi dish.
Flooding the river would be wanton genocide. Not that there are not many fans of genocide among them, just that it would hit both sides of the sectarian divide unacceptably hard.
Blowing the Mosul Dam would also be quite a feat for the Iranians - until they have nukes.
You’re using logic when it comes to genocidal maniacs .
Nothing they do should surprise you.
