Stabilizing fragile states is like trying to make sure a house doesn't fall apart. A fragile state is a country that has a lot of problems like poverty, crime, and political unrest. To make sure that the house (or country) doesn't fall apart, people need to fix the walls, doors, and windows.
In this case, the walls, doors and windows are things like the government, laws, healthcare, education, and economic development. By improving these things, it makes the house or the state stronger, and more stable.
For example, if the government has weak laws and does not do a good job of protecting people, then that makes the country weak and unstable. To make it stronger, people need to make sure the laws are enforced and protect everyone equally.
Similarly, if people do not have access to good healthcare, education, or economic opportunities, then this also makes the country weak and unstable. So people need to make sure that everyone has access to the resources they need so that everyone can get the help and support they need.
Ultimately, if the walls, doors, and windows of the house are strong, then it won't easily fall apart, just like if a state or country's government, laws, healthcare, education, and economic development are strong and stable, then the state will be stable as well.
