When US turned a blind eye to poison gas
'US Secretary of State George Shultz chose to say only that interviews with the Kurdish refugees in Turkey and 'other sources' (which remained obscure) pointed towards Iraqi use of chemical agents. These two elements did not constitute 'conclusive' evidence. This was the verdict of Shultz's British counterpart, Sir Geoffrey Howe: 'If conclusive evidence is obtained, then punitive measures against Iraq have not been ruled out.' As neither he nor Shultz is known to have made a further move to get at the truth, Iraq went unpunished.'
