Pakistan has placed an advertisement in the US media to reach out to America on 9/11. "Which country can do more for your peace", asks the advertisement in the Wall Street Journal . "Since 2001, a nation of 180 million has been fighting for the future of the world's 7 billion."
Dawn reported that Islamabad had initially given this advertisement to The New York Times but they refused to carry it. The ad says that since Sept 11, 2001, 21,672 Pakistani civilians have lost their lives. The army also has lost 2,795 soldiers. The country has lost $68 billion. The ad noted that despite sacrifices the country was still engaged in "the war for world peace". "Can any other country do so? Only Pakistan," it maintained.
