BBC:
Former World Bank chief Paul Wolfowitz has been appointed head of an influential panel advising the US government on arms control.
Mr Wolfowitz was ousted from the Bank last year over a scandal involving payments to his girlfriend, who was also a bank employee at the time.
He has long been a controversial figure in US and international politics.
As the Pentagon's number two after Donald Rumsfeld, he was one of the leading architects of the war in Iraq.
Juan Cole:
Hiring Paul Wolfowitz to advise the State Department on arms control is like hiring Lindsay Lohan as a driving instructor.
