Osama bin Laden is dead, but the troubling questions continue. It's far too early to declare an end of the war against terror. Bin Laden was only the ugly face of a hydra-headed terror monster that has been spreading tentacles in Pakistan, Afghanistan, Somalia, Yemen, Europe and America. But governments should remember that it is a monster best defeated by brains, not brute force.

The most difficult questions concern Muslim, nuclear-armed Pakistan and its relationship with the United States, Afghanistan and the world. Prime Minister Yousuf Raza Gilani gave a robust speech in defense of Pakistan, its armed forces and intelligence services without answering the questions: How could the world's most wanted terrorist have lived for six or seven years within a bullet shot of Pakistan's military academy and the headquarters of its controversial spy agency without them knowing he was there?

How in a country supposedly on constant alert against terrorists could no one ask questions about who occupied the virtual fortress in Abbottabad? Was it complicity or incompetence?
