If the chickensh!t UN feels it's safe to go back in, the situation must be dramatically improved.
The UN is ready to broaden its activity in support of Iraq, Secretary General Ban Ki-moon has said.
Mr Ban said at a key meeting in New York the time for determined action on Iraq had come, but that a greater UN presence would need better security.
The UN withdrew most of its staff in 2003 after a bomb killed its top envoy and 21 others but Iraqi PM Nouri Maliki says he can now guarantee UN security.
The secretary general said there would be a new "regional support office" in Baghdad to foster dialogue between involved countries and an office in the southern city of Basra was also being considered.
