A definition of insanity is the current campaign to "Close Guantanamo" by WitnessTorture.org.

Witness Against Torture, in combination with other groups, has launched The Fast and Vigil for Justice from Monday, January 11, 2010, which is the eighth anniversary of the opening of the detention facility for Guantánamo prisoners. The protest will continue through January 22, the date by which President Barack Obama pledged to close the detainee holding facility. 

The group makes this statement: “We act to draw attention to and oppose the administration’s trampling on the lives of the men - real people, not merely abstract "others" - at Guantanamo. In all, the Obama administration's handling of detainee issues-- from the reluctance to investigate and prosecute systematic torture, to its defense of indefinite detention—has fallen far short of the soaring rhetoric of his campaign. And now, and as the administration expands the war in Afghanistan and expands operations at the U.S. prison in Bagram Air Base in Afghanistan-- we see more clearly than ever the need for consistent, principled, nonviolent action and witness.”

Witness Against Torture is a grassroots organization that formed in December 2005 when 24 activists walked to Guantánamo to visit the prisoners and condemn torture policies. 

Since then, it has been involved in public education, community outreach, and non-violent civil disobedience. The group held a daily vigil at the White House, encouraging the new President to uphold his commitments to shut down Guantánamo for the first 100 days of the Obama administration.

In the meantime with this group's definition of insanity is the reality of increasing rates of recidivism for transferred Guantanamo prisoners. In recent days, several media outlets have reported on an updated report by the Pentagon’s Defense Intelligence Agency saying one in five former detainees have returned to militant activity.

At least one of the planners behind the Christmas Day bombing plot had been released to Saudi Arabia from Guantanamo Bay in 2007 and ended up rejoining terrorist ranks in Yemen.

You figure what you think about Witness Against Torture's definition of insanity.
