I can compare the relationships between and among contemporary countries.

To survive during all the wars, most of the countries ganged up on eachother. This is also known as forming allies. When they formed peace treaties with eachother and became allies, they were much stronger than single countries because of their ability to have backup wherever they went. They would listen to eachother on where to go and what to do, and it seemed to be the best way of fighting in all the wars back then that we used to have.
