Being a unique superpower undermines the military intelligence of strategy. To think strategically, one has to imagine oneself in the enemy's place. If one cannot do this, it is impossible to foresee, to take by surprise, to outflank. Misinterpreting an enemy can lead to defeat. This is how empires fall.
