Definition: Theocracy is a type of government in which a religious leader rules the country in the name of God.
Pros- They are able to solve problems a lot easier because they have to follow a set of rules. They are also able to get along better because they all have the same beliefs and values.
Cons - If a person in that country somehow does not follow the same religion, they could be discriminated and killed. The people there might not be as technologically advanced, because of their religious leader/God would tell them not to.

Gays are not only excluded from Iranian universities, but are imprisoned and killed." —Alan Dershowit
