Law 20 of 48 laws of power by Robert Greene says Do not commit to anyone.
Now Indian politicians sure follow this rule from heart. You will see them changing policies, principles, parties every election 😉
This is a smart tactic for power players and a suicidal trait for normal people, after a while no one will be around you! but for power players or those who move around in huge groups, it is intelligent to not display your inclination, favoritism, be as non partial as you can be!
