The United Nations Security Council is the primary international body in charge of upholding international peace andsecurity. Permanent and nonpermanent member states share in the responsibility to avert great power conflicts andthwart asymmetric disputes, regional instability and civil war, but the former task has priority and the prerogatives andtherefore the obligations of the five permanent member states widely exceed those of countries that hold two-yearelected seats. The bifurcation of roles nevertheless produces ‘responsibility shirking’, which weakens Council perfor-mance on the latter type of tasks. This article suggests that responsibility shirking is underreported in the literatureeven though it is well known to diplomatic practitioners. It considers three types of remedies to the situation, arguingthat amendments to the UN Charter or the Provisional Rules of Procedure are unlikely, but that piecemeal and prag-matic reform could precipitate a change of mindset. In particular, allowing nonpermanent member states to co-chairthe drafting of resolutions is likely to engage all member states in the core business of the Council.
