Answer:
The application of what I called the 3 R's :- Rehabilitation, Reconstruction and Reconciliation. These will help to unite a nation torn apart by civil war.
Step-by-step explanation:
For the country to be united, there is need to show judicious efforts towards it. This could be be declaration of "No victor, No vanquished " in-order to douse the tension between the warring factions.
Also, there should be immediate plan to reconstruct the areas destroyed by bombs during the war. Likewise in same light, plans should be set in motion to rehabilitate the people who experiences the war in terms of financial support to re-establish their business, visit hospital for counselling etc.
Lastly, there should be a judicial committee setup in-order to look into the grievances that led to the war and find a way to reconcile the people and resolve those issues.
