One way in which this division of power weakened the country.

Division of power tend to prolonged the legislation making process.

Explanation:

Division of power is initially created to prevent the government from becoming to powerful. We do this by dividing the government into three branches. The legislative branch to create the laws, the executive branch to implement the law, and the judicial branch to oversee the law

Even though this division is important, it has its own downside.

One of them is that it can prolonged the legislation making process. In order to pass a certain type of law, the legislative branch need to pass an examination made by the judicial branch and approval from the president on the legislative branch. Those branches do not always agree on key issues. This make the process to create a law become long and complicated.
