To mistreat a child is to start a war.
Wars come from wounded children who grow into wounded adults. Wounded adults need much and if they do not heal from their ill-fated childhoods, will most likely create wounds in others.
Imagine a group of power-hungry, wounded individuals trying to fill their emptiness with power over others. Of course these power-hungry mongrels are wounded because individuals not wounded do not need grandiose external power. Because these individuals do not have peace within they do not know how to create peace outside of them, thus they focus on retaliation, which is war thinking and they cannot create enough wars to heal their wounds.
To stop a war, any war, be it with a neighbor, a partner, a child, or a nation, the first step is to heal YOUR inside wounds, then and only then, will your wars stop and your outside reflect peace.
