The International Day of Peace, observed each year on 21 September, is a global call for ceasefire and non-violence. This year the Secretary-General is calling on governments and citizens to focus on nuclear disarmament and non-proliferation.
On 13 June 2009, Secretary-General Ban Ki-moon launched a multiplatform campaign under the slogan WMD – We Must Disarm to mark the 100-day countdown leading up to the International Day of Peace on 21 September.
During the 100 days of the campaign, the United Nations will raise awareness of the dangers and costs of nuclear weapons by issuing a reason a day on why nuclear disarmament and non-proliferation are so crucial, via Twitter and the social networking sites Facebook and MySpace. The Secretary-General has been joined in the campaign by United Nations Messenger of Peace Michael Douglas, who has championed the cause of disarmament for the United Nations since 1998, and American actor Rainn Wilson, featured in the TV series The Office.
