Halliburton, the largest US oil services company, is among a significant number of US companies that have sold oil industry equipment to Iraq since the UN relaxed sanctions two years ago.

From 1995 until August this year [the article was written in November 2000] Halliburton's chief executive officer was Dick Cheney, US secretary of defense during the Gulf war and now Republican vice-presidential running mate of George W.Bush.
