Answer: Have respect to maintain a friendly relationship between the countries of the world
Explanation: Respect is that line where the person must know when to act and when not to. When a country decides to invade another to obtain its own benefit, it is not having respect, it only thinks of its benefit and these are things that lead to a war being unleashed.
Respect can help other countries to be more considerate of each other, to think several times before invading a land that does not belong to them, and the opportunity for a better dialogue.
