At 42, Samantha Power became the youngest person to be appointed U.S. Ambassador to the United Nations. Now, she is a powerful force in steering America’s foreign policy and dictating intervention abroad.

The concept of sustaining peace—as enshrined in the identical General Assembly/Security Council resolutions of April 27, 2016—offers a new consensus and vision for the UN’s work, in which prevention plays a central role. Prevention continues, however, to be defined negatively, largely by its relationship to conflict rather than by a proactive, nationally owned strategy for averting the outbreak of conflict and sustaining peace.

Across peace and development initiatives, the exclusion of women comes at a high cost. Without women’s equal participation, peace agreements are more fragile, peacekeeping missions are less credible and safe, and economies are less prosperous.

The former state official of Estonia, Kersti Kaljulaid, was elected president of this country on past October 3rd in the parliament, Riigikogu. The sole candidate, 81 MPs out of 101 cast their votes in her support. Kaljulaid will serve as the first female president of Estonia, and she is the 17^th woman to currently occupy a position of Head of State/Government.

If Hillary Clinton wins the U.S. presidential election on Tuesday, the U.S. will join the roughly 50 percent of countries worldwide that have had a woman as the top national leader.
