In the face of those who deny this by stressing how the manner in which domestic institutions are designed affects such perspectives--for example, causing poverty--Thomas Pogge has shown how the existence of certain international rules promote the emergence of said domestic institutions.
The net effect of all these changes, Pogge calculates, is that, whereas world leaders pledged in 1996 that by 2015 they would reduce the number of undernourished people to no more than 828 million, now they are pledging only to reduce the number in extreme poverty to 1.324 billion.
Sin embargo, Pogge aduce que con el concepto de <<justicia global>> se ha intentado exportar el analisis moral institucional a las relaciones entre Estados, de manera que ya no es la sola etica la que rige tales relaciones, sino ademas los principios de justicia (Pogge, 2008: 99-103).
