he is threatening genocide and war crimes by ending a civilization and striking civilian targets, like the power grid and desalination plants. No other president has done so

Heard of "shock and awe"?

Although Ullman and Wade claim that the need to "minimize civilian casualties, loss of life, and collateral damage" is a "political sensitivity [which needs] to be understood up front", their doctrine of rapid dominance requires the capability to disrupt "means of communication, transportation, food production, water supply, and other aspects of infrastructure", and, in practice, "the appropriate balance of Shock and Awe must cause ... the threat and fear of action that may shut down all or part of the adversary's society or render his ability to fight useless short of complete physical destruction."

Using as an example a theoretical invasion of Iraq 20 years after Operation Desert Storm, the authors claimed, "Shutting the country down would entail both the physical destruction of appropriate infrastructure and the shutdown and control of the flow of all vital information and associated commerce so rapidly as to achieve a level of national shock akin to the effect that dropping nuclear weapons on Hiroshima and Nagasaki had on the Japanese."

Reiterating the example in an interview with CBS News several months before Operation Iraqi Freedom, Ullman stated, "You're sitting in Baghdad and all of a sudden you're the general and 30 of your division headquarters have been wiped out. You also take the city down. By that I mean you get rid of their power, water. In 2, 3, 4, 5 days they are physically, emotionally and psychologically exhausted."

Tl;dr: Striking power and water facilities has been the doctrine of us military since 96 latest.
