The Triple Alliance (Germany, Austro Hungary, and Italy)
Explanation:
The French and the Russian created the Dual Alliance which would mean that if France was attacked by a triple alliance nation, then Russia would field 700k troops to fight Germany and vice versa with France fielding 1.2 million troops to fight Germany.
hmm thats a tough one because an effective leader would need a little of both to know what to do in the times of crisis and then follow through with his plan.
