By increasing the number of suicide bombings against civilians and accepting their targeting in retribution, the insurgents sought to expose the weakness of the coalition-Iraqi security and reconstruction apparatus, threaten those who collaborated with the government, generate funds and propaganda, and increasingly enact sectarian revenge. The U.S. failure to adapt to this shift had dramatic consequences. By June 2004, U.S. deaths represented less than 10% of overall deaths on the battlefield and Iraqi deaths represented more than 90% - a figure that remained constant for the next 18 months of the War.
