Answer :
The reason why North Korea's citizens don't vote to change the leadership of their government is because:
1. North Koreans are not allowed to vote:
- In North Korea, the political system is structured in a way that doesn't allow citizens to participate in free and fair elections to choose their leaders. The government is controlled by the ruling party, led by the Kim dynasty, without the presence of competitive elections.
2. North Koreans can only vote for candidates approved by current government leaders:
- The political system in North Korea is centralized around the ruling party and its leadership. Citizens are only allowed to vote for candidates who are pre-approved by the government, limiting their choices and ensuring the continuity of the existing leadership.
By understanding these points, it becomes clear that the lack of voting rights and the strict control over candidate selection prevent North Koreans from having a say in changing the leadership of their government through democratic means.
