The annual Human Development Report normally concerns itself with the Third World, but the 2005 edition scrutinizes inequalities in health provision inside the US as part of a survey of how inequality worldwide is retarding the eradication of poverty.
It reveals that the infant mortality rate has been rising in the US for the past five years - and is now the same as Malaysia. America's black children are twice as likely as whites to die before their first birthday.
The report is bound to incense the Bush administration as it provides ammunition for critics who have claimed that the fiasco following Hurricane Katrina shows that Washington does not care about poor black Americans. But the 370-page document is critical of American policies towards poverty abroad as well as at home. And, in unusually outspoken language, it accuses the US of having "an overdeveloped military strategy and an under-developed strategy for human security".
"There is an urgent need to develop a collective security framework that goes beyond military responses to terrorism," it continues. " Poverty and social breakdown are core components of the global security threat."
The document, which was written by Kevin Watkins, the former head of research at Oxfam, will be seen as round two in the battle between the UN and the US, which regards the world body as an unnecessary constraint on its strategic interests and actions.
Last month John Bolton, the new US ambassador to the UN, submitted 750 amendments to the draft declaration for next week's summit to strengthen the UN and review progress towards its Millennium Development Goals to halve world poverty by 2015.
The report launched yesterday is a clear challenge to Washington. The Bush administration wants to replace multilateral solutions to international problems with a world order in which the US does as it likes on a bilateral basis.
