Mrigaula,

Krishna in the Gita teaches Arjun and the Pandavs how NOT to tolerate injustice to yourself over and over and over. Krishna taught the Pandavs that first you should try to negotiate peace. But if over and over and over people want to take you extending your hand in peace as a sign of weakness, then you collect your forces and you kicks some ass.

At a certain time, you gotta fight, for your right....to paaaaarty!
