Vajpayee went to Pakistan in bus 9 months after India's nuke tests
India conducted five nuclear tests in May 1998 under Atal Bihari Vajpayee's second term as Prime Minister. Vajpayee had then declared India a full-fledged nuclear state, the sixth nation to do so. Interestingly, just nine months later, the Delhi-Lahore bus service was inaugurated by Vajpayee, in which he travelled and was welcomed at Wagah Border by Pakistani counterpart Nawaz Sharif.
