The linked site is not very promising.
It lists the statistics of people suffering.
Not one solution nor, as this issue inevitably always ignores, the following:
1) Cultural conflicts: Polio vaccination has come to a halt in certain areas due to a mistrust, rightly earned, among some cultures against the vaccination program
2) Logistics. It doesn't matter one bit how much food is produced in the United States. There is going to be a cost to moving that food. It's that simple. Their is also going to be politics involved in moving that food and while the U.S. is the worlds leading food aid provider the methods involved are not in the best interests of those we aid.
3) Even more than logistics and culture. It's best represented by Somalia and Mogadishu when a band of warlords held and then ran out the world community. The warlords gave not one whit for the people who were dying. Somalia is once again facing famine. Their are pirates off the coast. The billions of tons of excess food do not mean anything without the will to do something about it. It seems Americans have forgotten the image of a soldier dragged through the streets of Mogadishu. In that instance, I think some groups will be glad of those missiles.:sarcastic
4) Religion. A tricky issue considering that Christian based missionaries do worlds of good in parts of the world regarding food, clean water, etc. However, along with that comes the baggage like Pentecostalism in Nigeria placing accusations of child witches. Whose ready to stand up and denounce the religion. The government of Nigeria has been slow to act. If their own government will not protect the children who will? An outside group? Scientists?
I'm not trying to be the naysayer but simplistic arguments such as military spending responsible for the lack of food aid worldwide is simply wrong. There are many more issues involved.
As the United States already involves itself through both private and government efforts in food aid then perhaps the U.S. government should revise it's methods to follow Europe and private groups in ending monetization programs on top of ending subsidies that are taken up by agribusiness in the States. Follow New Zealand. A more rational and less greedy approach to aid would help far more than simply diverting money from building ten stealth bombers. Which, by the way employed a large number of people and kept their families fed.
That and organizations need to make sure they do it right so that in places like Kenya when an outbreak of polio occurs after the vaccination program they are not accused of such things as "trying to sterilize Muslims.".
