How do the power balancing and power transition schools of the realist perspective differ on the question of when war is most likely?

Fill in the blank(s) with the appropriate word(s).

Varies. The power balancing school sees equilibrium as the most stable distribution of power and argues that war is most likely when one state tries to dominate the system (that is, to establish hegemony or empire). The power transition school sees hegemony as the most stable distribution of power and argues that war is most likely during a power transition, which is when a declining hegemon’s power is roughly equal to that of a rising rival or challenger.
