Not the OP but the US is purposefully starving the world. Not through direct means ala the British Empire in Ireland or India, but through upholding an economic and political regime that paralyzes many countries from being able to secure their own food supply. How this operates varies between regions, but most commonly poor countries' agriculture is heavily pushed by Western money towards export crops. As Thomas Sankara said of his own country, they had been able to feed themselves for thousands of years, so why after being ruled by France were they suddenly dependant on food aid?
Also if we agree that that chart is a good indicator of anything then China is the largest contributor and voted in favor of making food a human right.
Fair, I shouldn't have speculated like that. However, my argument is that the whole vote was a charade. If China knew the US was going to veto this, then their vote is meaningless.
This isn't the security council, or anywhere else, where the U.S. has veto rights. This (the Third Committee) seems to run on "majority yes" voting (i.e. if enough vote yes, it is adopted).
