First example was of arabia, where arab tribes had been in a constant war with each other. Holy Prophet(PBUH) taught the same people the message of love and brotherhood, and the same people went on to become united nation that rather than waging war against each other, ruled from spain to far east.

Seconly, european nations had been waging war against each other for long. Only once they decided to live with love and tranquility did they became an economic giant.

Hence, love is one such power that can help eradicate bad of war.
