Washington, DC: September 12, 2015. (PCP) Mr. John Kerry, Secretary of State in a message said that September 11 is a date seared into the minds of all of us at the U.S. Department of State and of citizens across America. Together, we honor the memory of the men, women, and children murdered in 2001. And we will never forget those who died three years ago in Libya: Ambassador Chris Stevens, Sean Smith, Glen Doherty, and Tyrone Woods. Each was a brave and dedicated professional; each was deeply committed to service on our country’s behalf; and each sought nothing more nor less than to help people overseas to live in freedom, dignity, and peace. Their example remains before us and – on this sad anniversary – our thoughts and prayers are with their families. This week also marks the opening to the public of the Flight 93 National Memorial in Somerset, Pennsylvania. The selfless heroism of the passengers on that flight saved many lives and serves as a permanent inspiration never to accept evil or to allow those driven by hate to achieve their goals. For that reason, there is no better day than September 11 to continue fulfilling our responsibilities in the home, workplace, classroom, and community. There is also no better time to move ahead with the business of American diplomacy – the unrelenting pursuit of peace, prosperity, human rights, and security in all its dimensions. Friends and adversaries alike should understand: the United States will never be intimidated by terrorists. Terrorists can cause tremendous suffering, but they can neither weaken our determination nor sway us from our purpose. For Americans at home and overseas, shared tragedy brings us together, adds to our vigilance, and strengthens our resolve not only on September 11, but every day of the year.
