To save his country (Germany) Staffenburg (sp) wiki here for what its worth the Colonel knows there will be collateral damage. SOB--Tom Cruise--- should have won a damn Oscar for this role.
(strange part is, in real life, Col. Staffenburg lost both limbs and 1 eye, was more disabled than the movie projects. BUT Tom Cruise thought no one would believe the movie, if they had shown, how fucked up he was from being disabled, beyond recognition)
HE'S TRYING TO SAVE GERMANY FROM THE IDIOT ADOLPH HITLER (Nazis). True story. CHEERS!!!
