LONDON – In 2015, the United Kingdom’s then-prime minister, David Cameron, stood before the United Nations General Assembly and challenged other donor countries to follow the UK’s lead and back the newly-minted Sustainable Development Goals (SDGs) for eradicating poverty with their aid money. “We haven’t just achieved the UN’s 0.7% [aid-to-GNI spending] target, we’ve enshrined it in law,” he declared.
