Since 1820 and till the beginning of the 21st Century, the so-called growing economic gap between the developed world and the developing countries has not changed its gloomy trend. The mentioned dismal tendency seemed to reverse only for a few years, during 1950 to 1973. In the 70s, the two oil-crises that unleashed inflation and reduced growth rates forced economic theorists and practitioners to look for a new economic policy. This economic restatement finally resulted in a shift of the pendulum, giving back the priority to the market forces, which to some extent had surrendered to the public sector since the 30s. This new economic restatement gave birth to a biased approach of the neoclassical model, which applied to international and development economics generated the so-called Washington Consensus. Against what was promised and expected, the recommended international economic policy did not ever work in the poorest countries, thus enabling the growing gap to continue. This phenomenon added to long-lasting unresolved international political problems along with the consciousness of constant neglect by the rich countries, has unleashed severe frustrations and in some cases induced the appearance of international terrorism. In our view, the policies of continuous insufficient international economic co-operation and biased trade negotiations with LDC, and the unfocused and somewhat over-done reactions to eliminate terrorism as practised in the last two years by western leadership, are doomed to fail.
