Nobody being willing to make large cuts is different from nobody making cuts. The US is not a member of OPEC, nor are several other oil producing countries: they don't follow OPEC but may still reduce output.

There is rumor OPEC isn't cutting production because they believe they can undercut their competitors and put them out of business - I don't think that is their motivation, but it is something that can't be ignored.
