She said the lack of "basic evaluation" in UN missions was

"shocking" and cited the example of the mission in Afghanistan that has been in place for over 15 years but has never once been reviewed.

Calling this "unacceptable", Haley said "we are in the process of proposing a strategic review of this mission and other missions to get the facts on the ground." With peacekeeping bring the largest item in the UN budget, she said the review will identify the missions in need of structural reforms.

"We will determine where we need to augment, re-structure and cut back," she said, emphasising that the US is supportive of "better and smarter" peacekeeping operations not the ones that are "cheaper."

"We have to have the political will to adjust the missions even if some countries are going to lose funding in the process," she said.
