3. What methods or tactics might a modem-day leader use to try to control his or her country and people

A modern day leader can use physical and psychological violence, remove an  individual and collective liberties from citizens, create fear and establish a government based on totalitarianism (meaning-a system of government that is centralized and dictatorial and requires complete subservience to the state).

Explanation:

To control a population, a modern-leader can base his government on physical and psychological violence. (not a great way if you ask me!) The leader can exercise constant and permanent vigilance over the life of the citizens, controlling even the personal and family life of certain people, that is, an extreme and excessive case of authoritarianism.

In addition, this leader can end the freedom of the population, establish a strong restriction in the media, among other many other things.

separation of powers, therefore, refers to the division of government responsibilities into distinct branches to limit any one branch from exercising the core functions of another.   the intent is to prevent the concentration of power and provide for checks and balances.  

the traditional characterizations of the powers of the branches of american government are:

* the legislative branch is responsible for enacting the laws of the state and appropriating the money necessary to operate the government.

* the executive branch is responsible for implementing and administering the public policy enacted and funded by the legislative branch.

* the judicial branch is responsible for interpreting the constitution and laws and applying their interpretations to controversies brought before it.

forty state constitutions specify that government be divided into three branches:   legislative, executive and judicial.   california illustrates this approach; "the powers of state government are legislative, executive, and judicial.   persons charged with the exercise of one power may not exercise either of the others except as permitted by this constitution."

while separation of powers is key to the workings of american government, no democratic system exists with an absolute separation of powers or an absolute lack of separation of powers. governmental powers and responsibilities intentionally overlap; they are too complex and interrelated to be neatly compartmentalized. as a result, there is an inherent measure of competition and conflict
