Only Vajpayee. Stood against USA and international sanctions after pokhran test, stready ecomonic growth, clear foreign policy (not like double standard UPA-Cong-Communists). Frankly speaking I am not talking from BJP point of view.
Indira - Black Emergency period, evil period of democracy, Khalisan-porblems and goonda-raj in election injected. Sold into the hands of KGB, Russia. Rao - Hawla scam, Urea scam, bribing MPs for getting majority in Parliament, sold into the hands of congress mafias.
