Washington faults Moscow for suspending inspections and cancelling talks under New START Treaty as tensions rise over Ukraine conflict.
While some are debating possible war scenarios, others think that Russia just wants to reach an agreement with the West on a new security architecture across its European borders.
If history is any kind of guide, then, Russian and American leaders will try to reinforce their respective spheres of influence in different parts of the world.
Signed in 2010, New START caps at 1,550 the number of nuclear warheads that can be deployed by Moscow and Washington, which control the world's largest nuclear arsenals.
The pact, which is set to expire next week, regulates the amount of strategic nuclear weapons that Kremlin and Washington can deploy. Once signed by President Vladimir Putin, the deal will be extended for five years.
Moscow reached out last week to request the call, according to US officials. Biden agreed but wanted first to prepare with his staff and speak with European allies, including the leaders of Britain, France, and Germany.
The New START deal, which was signed in 2010 and expires in February, limits the numbers of strategic nuclear warheads, missiles and bombers that Russia and the United States can deploy.

Moscow deploys its first regiment of Avangard, capable of carrying nukes at 27 times the speed of sound, a decision that President Vladimir Putin has boasted puts his country in a class of its own.
