“The nature of war has changed. It is fought now primarily against civilians” (Fintan O’Toole, Irish Times 3/18/22)
“…It is dead and injured soldiers who are now the collateral damage of war. Civilian casualties are the main event.
In the early 20th century, the ratio of deaths in wars was roughly eight soldiers to every civilian. By the end of the 20th century, this was reversed: one soldier died for every eight civilians.”

Germany’s foreign intelligence service claims to have intercepted radio communications in which Russian soldiers discuss carrying out indiscriminate killings in Ukraine.
In two separate communications, Russian soldiers described how they question soldiers as well as civilians and then proceed to shoot them, according to an intelligence official familiar with the findings who, like others, spoke on the condition of anonymity because of the matter’s sensitivity.
The findings, first reported by the German magazine Der Spiegel and confirmed by three people briefed on the information, further undermine claims by Russia that atrocities are being carried out only after its soldiers leave occupied areas. https://www.washingtonpost.com/world/2022/04/07/bucha-german-intelligence-radio-bnd-russia/
