President Biden is seeking a five-year extension with Russia on the only remaining treaty limiting the world’s two largest nuclear arsenals just days before it expires, said two senior U.S. officials.

At the same time, his administration is preparing to impose new costs on Russia pending a newly requested intelligence assessment of its recent activities. The officials said Biden is ruling out a “reset” in bilateral relations with Moscow as many U.S. presidents have done since the end of the Cold War.

“As we work with Russia, so, too, will we work to hold Russia accountable for their reckless and aggressive actions that we’ve seen in recent months and years,” said a senior U.S. official, who like others spoke on the condition of anonymity to discuss a sensitive security matter.

The decision to seek a five-year treaty extension, which Russia supports but the Biden administration hadn’t settled on until now, reflects the rapidly approaching deadline for Washington to renew the New START pact Feb. 5, the officials said.

President Donald Trump tried to conclude a shorter extension with Moscow in the final months of his presidency, but he failed to reach an agreement after his nuclear envoy spent months trying to persuade China to join the accord before dropping that demand. 

Letting the treaty expire would allow Moscow and Washington to deploy an unlimited number of nuclear-armed submarines, bombers and missiles in what many experts fear could spark a nuclear arms race and further exacerbate U.S.-Russia relations.

“New START is manifestly in the national security interest of the United States and makes even more sense when the relationship with Russia is adversarial,” the senior U.S. official said.

As the Biden administration informs Moscow of its terms for an extension, the president will order Director of National Intelligence Avril Haines to provide him a full intelligence assessment of Russia’s alleged interference in the 2020 election, use of chemical weapons against opposition leader Alexei Navalny and bounties on U.S. soldiers in Afghanistan, officials said. 

Biden is also asking Haines for an assessment of the massive cyberattack on federal agencies and departments related to the SolarWinds software breach, which many analysts and government officials have blamed on Russia. The request for the intelligence assessments will go out this week, said the officials.

“We will use these assessments to inform our response to Russian aggression in the coming weeks,” another senior official said.https://msn.com
