Always humanity had leaders, and some of them for different ideas, most religious ones, made war.
Love is not going to tell the Taliban to stop to attack, and in this case, there's no capital gain from the war, only territory.
Now shut up and think better before saying something.
Ah, and don't forget to grow up to forget those ideas.
Love is going to tell everyone to stop attacking. It will make everyone stop attacking, one way or another. Those that choose to live with ego will die and remain in a world like today, searching for love. Everyone has a choice to stay on an earth-like plane or find heaven. All you must do is believe.
