First of all, I am not saying anything about the current level of aid to Africa and the effect they have had. My OP was a what-if question. If the answer is nothing would happen, that’s what it is. Still, without doubting the knowledge of any of the respondents, I find it hard to believe that nothing would really happen.
Also, to be fair to the OP, We should be looking at US aid, only. We should also assume that whatever other help Africa is getting, should remain the same. The OP asks for diverting the Iraq effort to Africa. The Iraq effort is, mostly, a US effort.
This other WP article places the US help at 3-4 billions a year, to be upped to 9 billions. (other sources suggest that this is just a catch up to previously pledged but undelivered aid, but that is besides the point). This makes an additional 100 billion a ten-fold increase in US aid. And if it is world aid we are looking at, This SA paper estimates aid at 6 billion a year (and you would assume that an article wanting to talk about aid being wasted would want to offer the highest possible aid numbers). What would be the ultimate source for these statistics? UN? I am sure the numbers would vary wildly from source to source, depending on whether you count pledged vs. delivered funds; what programs are included and all that.
At any rate, I think that more than the money, which I completely agree is a total waste if it is handed to a corrupt government, the key factor here would be having the personnel to carry out whatever program is devised for those funds. 100 thousand men is quite literally, an army (the UN has 3000 volunteers in Africa, for comparison).
I agree that four years is a very short time to have a significant effect on culture. That would be the job of generations. I am open to other timeframes (and it is not as if Iraq is going to end tomorrow) as long as we don’t exceed the total amount of money and man-hours. Still, it is sufficient time for making a significant effect in the battle against malaria, for example; attacking the water problem; making basic infrastructure improvements; getting educational programs started, among other possible projects.
Excuse this WAG for a minute. I think (without knowing anything about it) that within my constraints, You could go a long way into solving the problem of water supply in Africa. This would in turn have a great effect on hygiene and disease control. It would also free people from a truly time-consuming chore and free their days for other tasks. A very minor change that would have a profound effect on the lives of many, an effect that would outlive the span of the project, that would not be opposed by the ruling thugs. I am sure better, more informed minds can think of better projects.
C’mon guys, an additional 100 billion dollars and 100K men on the ground. You say nothing good can come of this?
