Here's a concise definition of perpetual motion via wikipedia:
The term perpetual motion, taken literally, refers to movement that goes on forever.Here's a snippet of NPR reporting on a recent official report championing the evisceration of al Qaeda's leadership via CIA directed airstrikes:
CIA-directed airstrikes against al-Qaida leaders and facilities in Pakistan over the past six to nine months have been so successful, according to senior U.S. officials, that it is now possible to foresee a "complete al-Qaida defeat" in the mountainous region along the border with Afghanistan.Here's a nifty caveat in that report:
The threat of another al-Qaida terrorist attack against the United States has not gone away, they warn, noting that about 100 fighters have already "graduated" from the al-Qaida training camps and are prepared for possible terrorist operations in the West.Heh.
"Where those people are and what they're doing, we don't know," says one senior official.
