Argument: Assassinating Hitler would have been justified to end WWII
Fr. Williams Saunders. "Does the Church Condone Tyrannicide?". Herald Columnist. September 27th, 2001 - "Perhaps a particular example would help. In the Summer of 1944, many officers in the German military realized that their country would soon lose the war. The Allies had successfully landed in France with the D-Day Invasion and were pushing toward Germany; the Soviets were advancing from the East; the major cities of Germany were bombed heavily and frequently. To save Germany from devastating defeat and form a new government, Lieutenant Colonel Klaus von Stauffenberg, described as "a serious Catholic," formed a plot to assassinate Hitler on July 20. He and other members, including Field Marshal Rommel, Field Marshal von Witzleben, and General Beck, knew that Hitler had to be removed from power, and recognized that no regular means of government existed to do so. The only course of action seemed to be justifiable tyrannicide. Von Stauffenberg reportedly met with Cardinal Count Preysing of Berlin to discuss this matter, and his eminence honored the motives and offered no theological objection to restrain him. In so doing, Cardinal Preysing placed his own life in jeopardy with the Gestapo, but was never implicated in the plot.
On the evening of July 19, von Stauffenberg stopped by a Church to pray and then retired to bed. The next day, July 20, he planted the bomb at the Wolf’s Lair at Rastenburg in East Prussia. It exploded, but failed to kill Hitler. Von Stauffenberg and three others were arrested and executed that very night; others would endure the same fate later. However, they committed, or at least tried to commit, an act of justifiable tyrannicide."
