Final answer:
Countries could use nonviolent methods like diplomacy, negotiation, and economic cooperation to resolve differences, drawing on strategies and research provided by institutions like the Albert Einstein Institution.
Step-by-step explanation:
Instead of engaging in warfare, countries could settle their differences through various creative and nonviolent methods of conflict resolution, such as diplomacy, international negotiation, and mediation. Involving neutral parties in peace talks and utilizing international organizations for arbitration can often provide a platform for nations to communicate effectively. Economic cooperation and treaties, cultural exchanges, and policy dialogue are alternative strategies that promote mutual understanding and could prevent conflicts. The Albert Einstein Institution offers extensive research on nonviolent means for resolving conflicts which could be eminently useful in such scenarios. Moreover, achieving a more peaceful world often involves a deeper transformation of societies, highlighting the pursuit of spiritual regeneration, economic balance, and the employment of political bargaining instead of military might.
