Both the UN and the EU are effectively immobilized from taking action in a controversial situation by the requirement of unanimous agreement.

The meetings of the North Atlantic Council are chaired by the Secretary General of NATO and, when decisions have to be made, action is agreed upon on the basis of unanimity and common accord. There is no voting or decision by majority. Each nation represented at the Council table or on any of its subordinate committees retains complete sovereignty and responsibility for its own decisions.
