From the Document: "After meeting in Geneva on June 16, 2021, President Biden and Russia's President Vladimir Putin released a Joint Statement on Strategic Stability [hyperlink], which outlined their agreement on a path forward for nuclear arms control and risk reduction. In February, the two Presidents agreed [hyperlink] to extend [hyperlink] the New START [Strategic Arms Reduction Treaty] Treaty for five years [hyperlink] beyond its planned expiration on February 5, 2021. This treaty limits deployed long-range strategic nuclear weapons but does not address all types of U.S. and Russian nuclear weapons or other factors that could affect the risk of nuclear escalation or nuclear use. The joint statement addresses future discussions on these issues."
