Tell that to the families of those who were hung from piano wires. P.S. The film didn't mention the fact that Rommel was forced to commit suicide due to his knowledge of the plot.
The fact that they were executed in a gruesome way should stop me from stating the obvious truth? Most of them DID go along with the war, as long as it was promising success.
That's unfortunate. He had been recently wounded by an Allied fighter plane attacking his command car, but had been expected to make a complete recovery. Because the Western Allies respected him greatly due to his conduct of the North Africa campaigns, the conspirators wanted him to be the one who would approach the Western Allies with the proposed deal.
I suspect, however, that the reduction of Rommel's role in the movie had something to do with an insistence by Tom Cruise, or his agents. Compared to Rommel, von Stauffenberg was a nobody. A larger role for Rommel in the movie would have stolen some of his thunder.
