Hailing the valour of the armed forces during the Kargil war, Prime Minister Narendra Modi on Sunday asked people to speak and act keeping in mind the morale of soldiers and asserted that wars are fought not just on borders but on many fronts within the country too. In his monthly 'Mann ki Baat' radio address, which coincided with the 21st anniversary of Kargil Vijay Diwas, the prime minister also hit out at Pakistan for the conflict and said Islamabad responded to New Delhi's hand of friendship by stabbing it in the back.
