The adoption of Resolution 1820 last June was a milestone in the Security Council's efforts to protect women and a major step forward in the implementation of Resolution 1325. Last June Resolution clearly states that sexual violence in situations of armed conflict, when used as a war tactic, is a matter of peace and security, and therefore a responsibility of the Security ouncil. Women cannot participate effectively in the decision-making process unless their security is guaranteed, abuses are prosecuted, and blanket amnesties are off the table.
