The deliberate targeting of civilian life is a common though morally unjustified practice in modern wars. The during the Civil War, or War Between the States, General Sherman conducted total war on civilian life in the South. All the generals, North and South had been through West Point and learned the rules of Just War. In a letter to his wife, General Sherman mentioned that if the South were to win the war he would be hung as a war criminal.
During World War I there was Ottoman Empire’s extermination of the Armenians. This genocide resulted in an estimated one and a half million deaths. Ottoman Empire’s mass killing of Assyrians and Greeks are also added by many scholars to this same situation.
The illegal and unethical blockade of Germany, which continued for months after the Armistice, targeted civilian life. Some 800,000 German men, women, and children are estimated to have perished from starvation.
During World War II, the fire bombing of Dresden and Tokyo, plus the nuclear attacks on Hiroshima and Nagasaki, were violations of Just War. See also,
Allied War Crimes. Nazi war crimes are too well-known to need mentioning.

Korean War Attrocities
During Gulf War I, the U.S. in violation of Geneva Conventions and just war doctrine targeted civilian infrastructure in Iraq, such as the water treatment plants, the power grid, hospitals, etc.
Furthermore, the U.S. led embargo on Iraq was a war measure that targeted civilian life. Pope Paul II called the embargo “pitiless”. 567,000 Iraqi children under the age of five had died as a result of the sanctions (1995 U.N. Food and Agriculture Organization (FAO) report). Secretary of State Madeleine Albright said the
deaths of 500,000 children was worth it: In addition,
other casualty estimates.
Much can be listed about war crimes committed against the Iraqi population. I will mention here only that each planned bombing by the U.S. required a collateral damage estimate, which had to be pre-approved. Donald Rumsfeld signed off on the deaths of countless Iraqi civilians, whom the Administration merely considered to be “collateral damage.”
