I am looking for First World groups that do humanitarian work in the
Third World or are in partnership with groups in the Third World. 
However, I am specifically not looking for large development
organizations like the World Bank.  I am looking for organizations
that seek to ameliorate poverty, improve health, etc. by political
means.  The idea I'm looking to support is that causes for poverty are
often poltical and not incidental, and I'm trying to find examples of
groups that succeed working within this paradigm.  Websites of the
groups would be okay, but links to other sources (articles about these
groups, etc.) would be even better.  

I need this by tomorrow, or Thursday morning at the VERY latest.

Thanks!

Sarah2523,
I may not have exactly what you need, but I hope offering online
resources that might lead to that may help. I have rarely found
organizations whose web pages show what they think is the cause of
poverty.
Many articles do ascertain that Third World poverty is attributed to
Third World debt, and I consider that a political topic. I shall
mention links to articles about that below.


One possible organization:

I hope this gives enough resources to help. If you find a problem with
my answer, please post a request for clarification. Thank you.

Some experts have estimated that a large increase in standard of
living would be possible if we could reduce wasteful activities such
as war, crime, punishment, bad attitudes etc, so it is reasonable to
assume poverty is partly political.   Neil
