 According to Creveld, the capacity of Libyan ports were too small and the distances to be overcome too great for Rommel to advance a more ambitious plan than Hitler's original one of defending a limited area.Certain modern historians, such as Larry T. Addington, Niall Barr and Robert Citino, are skeptical of Rommel as an operational, let alone strategic, level commander.They point to Rommel's lack of appreciation for Germany's strategic situation, his misunderstanding of the relative importance of his theatre to the German High Command, his poor grasp of logistical realities, and, according to the historian Ian Beckett, his "penchant for glory hunting".
