Claiming that the defence of the country has been made "impregnable", Pakistan President Pervez Musharraf said on Sunday a comprehensive strategy is in place to ensure it goes from "strength to strength".Those on the "fringes of the society" and "obscurantist elements", who do not wish to see Pakistan on the path of progress and prosperity, should not be allowed to succeed, Musharraf said in his Independence Day message. Pakistan will celebrate its 60th Independence Day today."It is our collective duty as citizens of the state not to let such elements succeed in their evil designs," Musharraf said, adding "we have the example of our founding fathers before us to emulate. We cannot afford to let down the vast majority of moderate and peace-loving citizens".Musharraf said the defence of the country has been made "impregnable" and a comprehensive strategy is in place to ensure that it goes from "strength to strength." He claimed reforms and policies initiated during the last seven years have led to many achievements in all fields but there were still challenges ahead. (PTI)
