A man can give up a right, but he may not give up a duty without being guilty of a grave dereliction.
To see a promising solution to a dilemma and then just leave it to questionable development at its own pace without trying to aid its implementation would seem a dereliction.
In the lead up to the Iraq war and its later conduct, I saw at a minimum, true dereliction, negligence and irresponsibility, at worse, lying, incompetence and corruption.
