US Senator urges US authorities to extend START

She wrote about this in a letter published in The New York Times.

The senator noted that the United States and Russia own 90% of the world's nuclear weapons. Feinstein explains that ending START does not contribute to nuclear nonproliferation.

"The limitations of the (production - RT ) nuclear weapons treaty and its irreplaceable monitoring and verification mechanisms are vital to arms control," the senator said.

In July, Russian Foreign Minister Sergei Lavrov said that the fate of the START Treaty was apparently a foregone conclusion, the United States decided not to extend it.

On June 24, the United States announced its readiness "under certain circumstances" to consider extending the START Treaty. 

As noted by the Russian Foreign Ministry, Moscow does not intend to save START at any cost and is ready for it to cease to exist.
