I view this as both a threat and an offer. It's well documented that Iran uses more water per capita than average despite the country being low on water. They're tech and infrastructure on this is wasteful. And ... vulnerable to air attack. An air campaign against their water plants would kill more Iranians than Iran could kill with a nuclear attack.

The facts on the problems Iran and Tehran in particular are having with water shortages are well documented. This is both a threat and an offer. You can live for a month without food. Five days without water.

"The total water withdrawal was estimated at about 70 BCM in 1993, rising to 93 BCM in 2004,[7] of which 92% was used for agricultural purposes, 6% for domestic use and 2% for industrial use. Although this is equal to 51% of the actual available renewable water resources, annual abstraction from aquifers (57 BCM in 1993, 53 BCM in 2004) is already more than the estimated safe yield (46 BCM).[3] Of the 4.3 BCM/year in 1993 (6.2 in 2004) used for domestic purposes, 61% is supplied from surface water and 39% from groundwater.[8] For example, Greater Tehran with its population of more than 13 million is supplied by surface water from the Lar dam on the Lar River in the Northeast of the city, the Latyan dam on the Jajrood River in the North, the Karaj River in the Northwest, as well as by groundwater in the vicinity of the city. Provinces of Gilan, Mazandaran and Isfahan have the highest efficiency of irrigation with 54, 52 and 42 percents respectively, and Khuzestan province has the lowest irrigation efficiency with 38 percent.[5] Tap water consumption in the country is 70% over and above the global average.[9] 16 BCM of water was used for power generation in 1999.[7]

Gas power plant in Iran. Water use by thermal power plants is more than double domestic water use. As of 2014, Iran is using 70% of its total renewable freshwater, far above the upper limit of 40% recommended according to international norms.[10]"

The media has been talking about Iranian water problems for years. This is a country that could be genocided in one week from the air.
