Which of the following is a central tool of the UN action to consolidate peace?

Development assistance is considered a central tool of the United Nations' action to consolidate peace because it focuses on addressing the root causes of conflict and fostering sustainable economic and social development in post-conflict areas. By promoting development, the UN aims to create stability, reduce poverty, and enhance the capacities of nations to govern effectively and equitably. This approach not only helps to rebuild communities but also contributes to long-term peace by creating opportunities and fostering resilience against future conflicts.

In contrast, while military intervention may sometimes be necessary to address immediate threats, it is not a sustainable long-term solution for peacebuilding. Political treaties and peace treaties, while crucial in establishing ceasefires and frameworks for dialogue, may not adequately address the underlying issues that lead to instability. Development assistance, therefore, plays an essential role in linking humanitarian efforts with long-term development goals, ensuring that societies can thrive in a peaceful environment.
