1. Separation of powers is having separate branches of government to make sure that there is not one big powerful government.
2. Our government is divided into the executive, legislative, and judicial branches.
3. The ideas in the preamble are basically how the government is there for the people. When the government becomes too destructive, the people have the right to abolish it and create a new government. The decision to end the current government is not an easy one, and there should be clear reasons why. But when there is a long history of abuse of power, it is the peoples' right and duty to essentially fire the government. So, separating the powers of government would prevent the government from becoming too destructive.<span>

The Berlin Wall was built by the communist government of East Berlin 1961. The wall separated East Berlin and West Berlin. It was built in order to prevent people from fleeing East Berlin. In many ways it was the perfect symbol of the "Iron Curtain" that separated the democratic western countries and the communist countries of Eastern Europe throughout the Cold War.
Hope this helps!
