Cheney defines Bush Doctrine in 2001

There are about 5 different definitions of Bush Doctrine that I've found so far.
But this one is interesting to me, because it was said by VP Dick Cheney, shortly after September 11. Its from October 23rd of 2001.

Under the Bush doctrine, a regime that harbors or supports terrorists will be regarded as hostile to the United States of America.

The direct attack on our nation has put us on notice that the enemy is resourceful and ruthless. We have to assume there will be more attacks. That is the only safe way for to us proceed.

In this conflict, for the first time in our history, we will probably suffer more casualties here at home than will our forces overseas. But in the face of these dangers, Americans can be assured that we are doing absolutely everything we know how to do.

Its strange to believe that September 11th happened 7 years ago. It feels like 2, maybe 3 years ago. Anyway, I thought that the next time that Charlie Gibson asks someone about the Bush doctrine, he might want to use Cheney's definition.
