Wars with more than three participants are called complex wars, and they are longer and more uncertain than dyadic wars that are wars between two states. Dyadic wars are simpler in comparison to complex wars since there are only two foreign policies, sets of motives, and interactions. Dyadic wars are more prone to break out between neighbor states over territorial disputes while complex wars are more likely to exhibit
complex power politics (Vasquez and Valeriano, 2010: 294-296).
