Divide and conquer
It is all part of a divide and conquer strategy. Break the place apart, section by section, entity by entity, group by group and department by department until you have a fractured environment where supporting each other actually becomes a battle for life. This style of management is nothing new, but just remember what happenned to Napoleon, what happened to Alexandar the Great, what happenned to mighty Rome? Short, smart people (supposedly) who thought they were indestructable, insurmountable and untouchable.
