How about the 8-12 million landmines, of which approximately six million were sold to Iraq by the U.S. The U.S. knew that Iraq was a rogue state, and that it had used gas on the kurds, which was one of their major arguments for entering Iraq in the first place (WMD's, supposedly), and that the gas itself was sold to Iraq by the US.
Also, many of the bunkers were designed and built by German companies. It's all one big dangerous game, and everyone is involved all the 'friendly' nations including us, and i say this again, because it sounds like people believe that i think the UK is resolved from blame, which i do not.
Ok, fair enough about the stingers, i'm not up-to-date with that obviously, but they were concerned about them post Afghan War.
