Many strategic principles work only in specific relationships of size. What works fine for David's attacking Golliath fails completely when Goliath tries it against David. A small organization works against a larger rival differently than a large organization works against smaller rivals (3.4.2 Scale Limitations). One set of methods grows organizations, a very different set keeps them on top. A whole set of classic errors come from a misunderstanding of scale.
Obama's attack on FOX News is a perfect illustration of this mistake. As president, he is using a classic strategy (9.2.5 Vulnerability of Organization), but because he is the larger of the two, instead of driving other news organizations away from FOX , this move created the reverse situation (3.2.5 Dynamic Reversal), forcing other news organizations and other Obama allies to defend FOX.
