A war veteran and the only Hindu member of the US Congress, Tulsi Gabbard is our newsmaker on The Buck Stops Here. She tells NDTV, US should not be policing the world, instead it should regain focus on defeating "Islamist extremism". She speaks about her experience of being a non-Christian politician in the US and how Bhagvad Gita teaches us that wisdom is not the preserve of any one religion or faith.
