From the Socialist Party USA website:
In 2015 we mark the 70th anniversary of the United States atomic bombings of Hiroshima and Nagasaki. It also marks 45 years since the first five nuclear powers agreed in Article VI of the Nuclear Non Proliferation Treaty (NPT) to undertake good faith negotiations for the elimination of their nuclear arsenals.
Join the Socialist Party USA at the Peace and Planet action from April 24 -26, 2016. Check out the Anti-War Campaign website fro [sic] logistics on March 1st.
