They did not kill all the POWs. But IIRC, there is no existing German language recording of a Declaration kf War against the US. But, just as America wanted to fight the japs after Pearl Harbor, America equally badly wanted no part of the "European War" , remembering WWI. How did we go from NOT wanting to fight the Germans, to "Germany First"? To me, the answer is this: jewish influence on Roosevelt to force the issue. The same jewish influence that directed Eisenhower to build massive POW camps after both the No. African Campaign, and the end of the war in Europe. This is where many thousands of surrendered troops, protected by the Geneva Convention, were starved and/ or allowed to die of disease As James Baker said: " Once the war drums beat, and the Allies ramped up the propoganda against Germany, they could not just switch it off. Again, the jews constant pressure to remember the war brings us to to today; it is "Anti semitic" to even question the narrative
