FOX News takes an exclusive look at what motivates Defense Secretary Donald Rumsfeld and what makes him so controversial.

We'll examine why President Bush stands behind him and what drives the 73-year-old Rumsfeld to soldier on.

We'll show you how Rumsfeld set out to transform the U.S. military from a force designed to win past wars to make it faster, lighter, more efficient.

We'll examine how Rumsfeld used that concept to win a lightning victory in Afghanistan and, in the process, became one of America's most popular and admired leaders.

But that would change, however, with next front in the War on Terror: Iraq

We'll break down the success of Operation Iraqi Freedom, the ongoing battle to rebuild a nation that toiled for years under a brutal regime and why Rumsfeld faces heavy fire at home.
