From a Guardian editorial of 14 November:
There is another lesson to the Petraeus affair. The former general fashioned for himself a role, which is much more significant than top generals have during wars. [screengrab]
Readers may briefly infer that what is “much more significant” is not a role but Petraeus’s fashioning a role for himself, or they may infer that top generals don't normally have a role during wars.
