Recently, the Russian President announced that Moscow was suspending its participation in the New START treaty with the United States.

About New START Treaty:

  • It is known as The New Strategic Arms Reduction Treaty (New START).
  • It is the last remaining nuclear arms deal between Russia and the United States of America, and it was extended for five years in 2021.
  • Objective: The New START caps the number of nuclear warheads well below Cold War limits. 

What is the timeline of this treaty?

  • New START continues the bipartisan process of verifiably reducing U.S. and Russian strategic nuclear arsenals begun by former Presidents Ronald Reagan and George H.W. Bush.
  • The treaty was signed by US President Barack Obama and Russian counterpart Dmitry Medvedev in Prague in 2010.
  • New START replaced the 1991 START I treaty, which expired in December 2009, and superseded the 2002 Strategic Offensive Reductions Treaty (SORT), which terminated when New START entered into force.
  • Both Russia and the United States announced that they met New START limitations by Feb. 5, 2018.
  • Importance: New START is the first verifiable U.S.-Russian nuclear arms control treaty to take effect since START I in 1994.
