Actually, Ford and GM had very little control over their overseas divisions. The suits thousands of miles away in Detroit had far less input than the Waffen-SS officer ten yards down the hall with a StG44 did.
One of the Krupps I talked to went to the University of Chicago prior to the war to learn the latest in metallurgy to take back to Germany.
Relevant words bolded.
Any director of GM or Ford could be accused of Nazi leanings.
The only one that truly applied to was Henry Ford himself.
There is an interesting sidelight to the war that was observed by our troops in Germany. There was never a bombing run on any of these factories connected to our automakers and Krupp, even though they were involved in supporting the war effort of the Axis.
Since the circular error probable for a bomb run was five miles in those pre-LGB/JDAM days, your claim is garbage.
People in high places wanted those factories intact when the war ended.
Which explains why Ford and GM got tens of millions in compensation for damage to those factories when they got bombed and/or shot up during ground fighting in the course of the war.
It is hard to control a group of ground forces when the enemy is using a site as a defensive position. Krupp Steel was very heavily involved in the V2 rockets that were used against England in the Battle of Britain. As far as the JDam comment being a bunch of garbage, I would advise you that every building in Schweinfurt housing their ball bearing factories were leveled, not by pin-point accuracy, but by massive bombing.
A five mile radius as you mentioned is a little off the mark, the bombardiers were capable of coming within a half mile at 10,000 ft. altitude in spite of wind, drift, and density. Our artillery was capable of pin-point accuracy up to eight miles after several rounds spent getting on target. The ballistics and quality of our bores would hold the rounds within a five foot circle at eight miles. The variables such as changing wind speed and direction, incoming moisture and cold fronts would cause a parameter to widen but could be overcome in a round or two after adjustments.
