Powell Doctrine

The "Powell Doctrine" is a journalist-created term, named after General Colin Powell, for a doctrine that Powell created in the run-up to the 1990–91 Gulf War. The doctrine poses nine questions, emphasizing national security interests, overwhelming strike capabilities with an emphasis on ground forces, and widespread public support, all of which have to be answered affirmatively before military action is taken. Powell's doctrine is based in large part on the Weinberger Doctrine, devised by Caspar Weinberger during his tenure as Secretary of Defense (at which time Powell was Weinberger's senior military assistant).
Summary.
The Powell Doctrine states that a list of questions all have to be answered affirmatively before military action is taken by the United States:
As Powell said in an April 1, 2009 interview on "The Rachel Maddow Show", it denotes a nation's exhausting of all "political, economic, and diplomatic means", which, only if all were futile, would result in the condition that the nation should resort to military force. Powell has also asserted that when a nation is engaging in war, every resource and tool should be used to achieve decisive force against the enemy, minimizing casualties and ending the conflict quickly by forcing the weaker force to capitulate.
Analysis and commentary.
The Powell Doctrine has been reported as an emerging legacy from the Korea and Vietnam wars and the "Never Again vs. Limited War" policy debates (either win or don't start versus value of limited war) and Weinberger's Six Tests described in his 1984 speech "The Uses of Military Power". It has been used to compare the Vietnam War, the Gulf War, and the Iraq War.
