Answer :

When countries fail to establish justice, security, and the rule of law peace and stability are the first to suffer.  A breakdown in the rule of law may slow the road to reintegration after a conflict, cause or exacerbate violence and tensions, and fuel criminality and insecurity. Only when societies are able to implement and abide by the rule of law, can they also achieve other critical milestones, such as inclusive and effective governance and the respect for human rights.
In simple words- 
The rule of law can help our country by making it stable for example there would be less conflict also its good for our safety. Furthermore protects the people's own rights.
