By bestowing just "Bharat Ratna" to Shri Atal Bihari Vajpayee, it'll equate his contributions to likes of Indra Gandhi and Rajiv Gandhi. I think, it'll be utterly unfair. Bestowing will be just first step in right direction.
Remember, it's was under Shri Vajpayee's leadership, India could think of becoming something in economic arena FIRST time in our history. He gave hope to billions of people who're seen like poor and weak thanks to communist policies of Nehru family followed over six decades.
First time in India's history, it was proven that coalition can provide economic and political stability adding much-needed concept to Indian democracy. Nehru family's contribution is just their whims to political process in this country.
We only have to think if "Bharat Ratna" is enough recognition to his contributions.
