How come even the BBC uses language like this? "About 15,000 more US soldiers and reservists have been told to prepare for service in Iraq because of the failure of other countries to contribute soldiers. " BBC NEWS | US and Russia warn Iran

Perhaps it's not a "failure" but a "refusal". "Failure" implies a normative which doesn't seem to exist.

BTW there's a lot of warning Iran about a nuclear weapons program that Iran denies. But given Iraq and North Korea do we have any reason to believe that this is more than a scare story based on spun circumstancial evidence?
