We should live in peace and love instead of fighting with each other

As much money as we have used to fight each other, if we had invested in supporting each other and doing each other's work, no country in the world would have been poor, a rich country would have cooperated with poor countries and No poor country would live. As much weapons as we have bought, if you had bought food with different money, no one in the world would sleep hungry. We would have built a house with the amount of cloth we bought, so no poor person in the world would have slept without a roof. What is needed is not weapons and fighting each other
