This comment from Tom is worth repeating:
It's worth quoting the whole of the section of the executive summary of the Commons International Development Committee on South Sudan: "UNMISS...has been slow to produce a peacebuilding strategy. UNMISS is also a hugely expensive operation, costing the UK taxpayer £60 million in its first year—two thirds of DFID’s annual development and humanitarian budget. UNMISS does not currently provide value-for-money and its resources have not been deployed most effectively. The UK Government should press the UN for an urgent review of UNMISS’s cost, mandate, assets and operations."Here is the link to the full report.
