Wiki-leaks good or bad.?

The Pentagon is demanding the removal and retrieval of all doents pertaining to the war in Afghanistan recently posted on Wiki-leaks, as well as a further 15,000 not yet online, as is their right. My question is Wiki-leaks good or bad, should they remove the files or keep them online. Do they work to better the U.S. military and political practice or damage it. Thanks for replies.
