While I agree on that in general, I've a bit of a hard time seeing that fully for Cohn. Tried to use his influence, which clearly worked for some time, to stave off a decision he thought is bad. Once his influence was proven to be gone, he made the decision to leave.https://twitter.com/qjurecic/status/971160831797932032 …
Obviously dangerous to fall into trap of thinking you can do some good, but Cohn *did* seem to have an effect in controlling some anti-trade policies.
