Eisenhower's Death Camps were set up in the Rhine meadows immediately after WW2.
Hundreds of thousands of regular german POWs were forced to starve in the open fields for months with little or no food/water and no shelter. A blatant violation of the rules of war as specified in the Geneva conventions.
An unknown number of germans died from this deliberate, but extremely under-reported, mass-murder.
The Rhine meadows death camps is just one example of the many war-crimes committed by the "allies" during the WW2 era.
