What many problems ? And, about sources : the article in Der Spiegel is quoting what Ruge was saying, and as Ruge is not a neutral person ..... Shortly after the war (september 1945) Lucie Rommel denied categorically that her husband was involved in the 20 july . A few years later,at the start of the Cold War, for obvious reasons, some people in Germany started the Rommel myth, and Ruge and Speidel used this Rommel myth for their career , that's why Ruge edited his diaries to transform Rommel in an opponent of Hitler,and to protect Speidel : if it had been known that Speidel betrayed Rommel to save his own neck, Speidel could forget his career . The same for Ruge : if in 1955 his opinions about the Jews had become public, it was over and out for Ruge . Both had a lot to hide .
