The Council on 4 December 2014 agreed on a set of guidelines to complement the Revised EU Strategy for Combating Radicalisation and Recruitment to Terrorism, endorsed in June 2014. Under point 2 of the guidelines "in order to ensure that new and emerging threats are effectively addressed, it is necessary to monitor these guidelines and the priority setting therein, as well as their implementation and to adapt when needed". Furthermore and according to the guidelines, point 4, the state of implementation and the guidelines should " be reviewed every two years and updated where appropriate in order to ensure effective action at national and EU level in view of the changes of the terrorist environment".
