Richard Jolly and Deepayan Basu Ray, in their UNDP report, suggest that the key criticisms of human security include: Human security does not have any definite boundaries, therefore anything and everything could be considered a risk to security. This makes the task of policy formulation nearly impossible; Human security, when broadened to include issues like climate change and health, complicates the international machinery for reaching decisions or taking action on the threats identified; Human security risks engaging the military in issues best tackled through non-military means; Human security under the UN risks raising hopes about the UN's capacity, which it cannot fulfil.
