It's a conflict that pits the might of America and its allies against Osama Bin Laden's terror network.

Who is now winning the "war on terror"?

Since September 11th, Panorama has followed the hunt to destroy Bin Laden and his network.

Billions of dollars have been spent and thousands of soldiers mobilised across the globe.

But with Bin Laden and most of his lieutenants still at large, what has the war actually achieved?

The terror network still stalks the west and al-Qaeda threatens new attacks, even more deadly than what happened in New York and Washington.

And US Senator Bob Graham, head of the Senate's Intelligence Committee, has told Panorama he is convinced Osama Bin Laden is still alive.

Trailing the enemy

We follow the war across its battlefields in Afghanistan: to Tora Bora where Bin Laden was allowed to escape, to the valleys of south eastern Afghanistan where the US launched a full scale military offensive against the network, and to the Pakistan border where the British try in vain to find remnants of the network.

As this happens we show how the terror network has responded and learnt from its mistakes.

With attacks on civilians in Tunisia and Pakistan, al-Qaeda has continued to bring terror in spite of the war waged on it.

From the front line

The film has extensive documentary access to US and British soldiers in Afghanistan.

We follow a group of American infantrymen as they locate and destroy al-Qaeda caves and develop a new understanding of their foe.

We show what life is like for them on the new front line.

And we follow the frustrating efforts of a British helicopter pilot and of marines to find traces of their enemy.

Since 1998 Jane Corbin has made a number of investigative films about Osama bin Laden and al-Qaeda for Panorama. In Towards the Zero Hour, a one-hour special on BBC One last December, Jane investigated the terror cell, led by Mohammed Atta, which planned and executed the World Trade Centre attacks.
