Washington mulling New Strategic Arms Reduction Treaty extension past 2021

The United States has not decided yet whether it will extend the New Strategic Arms Reduction Treaty (New START) with Russia, the US deputy assistant secretary of defense for nuclear and missile defense policy said, Sputnik reports.

"We say in the NPR [Nuclear Posture Review] that we will live by the treaty. We haven’t made a decision yet," Robert Soofer told RIA Novosti in response to whether the treaty would be extended by another five years.

The nuclear arms reduction treaty was signed by the United States and Russia in 2010 and came into effect the following year. It is due to expire in 2021.
