President Asif Ali Zardari on Monday again made it clear that democracy will be strengthened in the country no matter what price we pay as we will not allow the democratic system in the country to derail at any cost. President expressed these views on the eve of the third anniversary of the Karzaz tragedy in his message on Monday. PPP Co-Chairman and President Asif Ali Zardari paid glowing tributes to the martyrs. He said the tragedy was a reminder that the central battle in Pakistan was the battle between the forces of moderation and democracy on the one side and that of extremism and religious bigotry on the other. Shaheed Mohtarma Benazir Bhutto was the symbol of resistance against militancy and bigotry and the attack on her on this day was indeed an attack on all forces of moderation, he said. We must win this battle if we are to survive as a modern, moderate and democratic nation where ballot and not bullet will determine the direction we take, he said in his message. Those who laid down their lives on this day three years ago are the heroes and heroines of the battle against extremism. They have lit the path with their blood for future generations to traverse in the fight against obscurantism, militancy and extremism. They did not die in vain; they gave up their lives so we lived in freedom, dignity and hope. The martyrs of Karsaz are the strength of the nation and we salute their courage and loyalty, he said adding, Even in a distant age and clime they will serve as inspirational models and motivate people to fight the bigot and the militant to the finish. Nearly two hundred Jan-nisaran-i-Benazir, fans of democracy and ideological foes of militancy were martyred in Karachi on this day when the terrorists struck the convoy welcoming the icon of moderation Shaheed Mohtarma Benazir Bhutto on her return journey to Pakistan from almost a decade in exile. On this day let us all commit to continue the fight against extremism. Let us also on this day vow to uphold the principle of parliamentary democracy in which the people through free and fair vote at regular intervals decide the fate of the country, and not a handful of individuals, the PPP Co-Chairman said. On this day I wish to reiterate that we will root out militancy and extremism from our land and strengthen democracy in the country no matter what the price, he added. He said that the government has taken measures to rehabilitate with respect the families of those who laid down their lives to protect Shaheed Mohtarma Benazir Bhutto. This is our duty and we will do more to honour the families of heroes of democracy, the PPP Co chairman said.
