Ukraine limiting irrigation water to Crimea is peanuts compared to historical examples such as Free French Air Force participating in months of severe bombing of road and rail networks, bridges, railyards and other critical infrastructure of occupied France in preparation for the Normandy landings.
Or to to cite a more recent example, like the Russian armed forces mudering thousands of its "own" people in the siege of Mariupol (these being the 80 percent or so of the population who were Russian speaking, across the 5k-20k civilians estimated to have been killed). And damaging or destroying 90 percent of the buildings they used to live and work in.
