Meta, I think you are misinterpreting what I am going for. When I mean self sufficient, I mean that the country econonic and social development progresses strongly on its own accord without the need of aid from other countries. Trading goods and services aid in that, because that brings in resources not normally availabe yet given on a more or less even playing field, depending on market forces. One of our, meaning the US, major dependency is foreign oil but if we reach a technological and resource stage which we no longer need foreign oil we will be a stronger position of self sufficiency. I think that is something worthwhile to achieve.
Also I think it is necessary for other nations to work towards not needing foreign aid on a yearly basis. I think it would be a major accomplishment if Iraq became economically and socially self sufficient, meaning that its exports and imports of trade goods make it no longer needing US or any other country's assistance. That is what we need to achieve in both Afganistan and Iraq in order for those countries to be truly free and autonomous.
