Those range from a simple pledge to resume regular negotiations to seek further reductions, to a more ambitious but nonbinding public commitment to reduce current arsenals, if only modestly, as a goodwill gesture for future negotiations.
The fact that these recommendations come from military and diplomatic veterans in both countries sets the issue apart from the host of other thorny security issues crowding the summit agenda where there appears to be little if any diplomatic daylight. Those include Russian election meddling and cyber attacks to its invasion of Ukraine and support of the Syrian governmentโs massacre of civilians.
โThereโs going to be tons of airing of differences and grievances, but I think there also is some opportunity for progress on the area of strategic stability and arms control,โ said Lynn Rusten, previous senior director for arms control and nonproliferation on the National Security Council during the Obama administration and an ex-State Department official. โI think the whole meeting is going to provide a new grounding.โ
No one is banking on detailed agreements to emerge from Geneva; even the definition of strategic threats has only grown more complex now that cyber attacks, political warfare and other forms of mischief can destabilize entire nations as massive military conflict could in previous generations.
But both governments have been striking a similar tone in recent days on the nuclear front, at least rhetorically.
National security adviser Jake Sullivan expressed the administrationโs desire to get back to a regular dialogue with Moscow on nuclear matters as a first step. โWe believe the starting point for strategic stability talks should be the very complex set of nuclear arms issues that face our two countries,โ he told newsmen ahead of Bidenโs European trip.
Sullivanโs comments came a day after Russian Foreign Minister Sergey Lavrov, in typically verbose Russian diplomatic language, also hinted at a desire to reach common ground on nuclear issues as part of broader discussions.
โWe advocate a comprehensive approach and taking into account all, without exception, factors influencing strategic stability in our dialogue with the United States,โ he said. โI mean nuclear and non-nuclear, and offensive and defensive weapons.
โAnything that affects strategic stability must be discussed during a dialogue,โ he continued. โI hope that, based on the preliminary work and consultations in preparation for this summit, President Vladimir Putin and President Joseph Biden will be able to determine a strategic policy for future work in these areas.โ
A common push
Both presidents are also getting a rare push from a range of respected voices who spent decades in government trying to avoid a U.S.-Russian nuclear conflict.
Previous nuclear officials and arms control experts in the United States, Europe and Russia have jointly issued a flurry of recommendations for how to revive a formal dialogue to reduce the nuclear danger.
โClashing national interests, insufficient dialogue, eroding arms control agreements, advanced missile systems, and new cyber and hypersonic weapons have destabilized the old equilibrium and are increasing the risk of nuclear conflict,โ a loose collection of notables calling themselves the Euro-Atlantic Security Leadership Group wrote in outlining a series of principles to guide Biden and Putin.
The signatories include a range of previous military leaders and strategists who served on opposing sides of nuclear war planning, such as the ex-head of Russian strategic rocket forces and the top U.S. and NATO military commanders in Europe. Also lending his voice was Putinโs first foreign minister and previous head of his security council, Igor Ivanov.
At minimum they are urging Biden and Putin to declare in a joint statement that both countries are devoted to regular, senior level talks to discuss โstrategic stability,โ a process that foundered over the last four years, in which both sides met face-to-face only twice.
โWe can't have strategic stability without dialogue,โ the arms control veterans wrote. โThe absence of dialogue erodes stability. The tools of communication are not being used as they should be.โ
In a separate public appeal, U.S. and Russian nuclear veterans also called on both leaders to โcommit to a bilateral strategic dialogue that is regular, frequent, comprehensive and result oriented leading to further reduction of the nuclear risk hanging over the world and to the re-discovery of the road to a world free of nuclear weapons.โ
Modest expectations
Both leaders are believed to be going into the day-long summit with the intention of reaching some agreement on the way forward even if most of their meeting is spent leveling charges and countercharges.
โI think arms control is seen as the only area where progress is possible,โ said Nikolai Sokov, a previous Russian Foreign Ministry official who helped negotiate several arms control agreements between the United States and Russia. โBoth sides want to isolate arms control from the rest of the issues.โ
โI think we're going to see some progress there,โ Sokov, who is now a senior fellow at the Vienna Center for Disarmament and Non-Proliferation, added in an interview. โIt's hard to know exactly how much progress, but I would say the most likely outcome is they will decide to launch some strategic stability talks on the issues. Maybe they will give it a different name. Whatโs really needed right now is what is the scope of the agenda, what will be on the table?โ
Daryl Kimball, executive director of the Arms Control Association, a leading disarmament group, also said he is hopeful that an agreement to restart formal nuclear talks is in the offing.
โBoth governments, not just both presidents, have made it clear that they see that as being their own self-interest and mutual interests,โ said Kimball, who met with Bidenโs National Security Council staff ahead of the summit to discuss ways that such a dialogue could be developed.
โStrategic stability talks are fundamentally about reducing the factors that can increase the risk of conflict spilling into the nuclear realm,โ he added. โIf they donโt achieve that, it will be very disappointing.โ

Just days after Biden took office in January, the United States and Russia agreed to a five-year extension of the New Strategic Arms Reduction Treaty, which limits both sidesโ most powerful nuclear arms to 1,550 deployed weapons. But there is little agreement on what might come next for further arms control agreements.
The Russians have insisted publicly that any future pact must also cover missile defense systems, which Moscow views as destabilizing and Lavrovโs pre-summit statement alluded to when he referred to a desire to discuss โoffensive and defensive weapons.โ That has been a non-starter for U.S. negotiators for years.
The United States, meanwhile, has maintained that Russiaโs thousands of reported tactical nuclear weapons, which are not covered by New START, must also be on the table. Russia is believed to maintain significantly more battlefield nuclear weapons than the United States.
One of the most complex issues involves shorter-range nuclear-tipped missiles that were previously banned by the Intermediate-Range Nuclear Forces Treaty, a 1987 pact that Russia violated and both countries recently scrapped.
โWeโve extended New START for five years. But what follows that?โ Sullivan asked the previous week. โHow do we deal with the fact that the INF Treaty is no more, how do we deal with our concerns about Russiaโs new nuclear systems?โ
Setting the agenda
One of the recommendations offered by the arms control advocates ahead of the summit is for Biden and Putin to โimplement a ban on the deployment of Russian and U.S. land-based INF-range missile systems.โ
NATO leaders issued a communique on Monday in which they declared "we've no intention to deploy land-based nuclear missiles in Europe."
But a number of close observers see it as unlikely that Biden and Putin will make such a pledge, given the Russian violation of the INF Treaty and little confidence in Washington that Moscowโs word can be trusted without strict verification measures.
โRussia has deployed nuclear missiles in Europe. Thatโs why the INF Treaty doesnโt exist anymore,โ said Tim Morrison, a senior fellow at the hawkish Hudson Institute who was deputy assistant to President Donald Trump for national security. โSo are we making a unilateral concession? Thatโs never a good idea. Even if it was a bilateral agreement that either the U.S. or Russia deploy nuclear missiles in Europe, Russia couldn't honor it when it was a treaty. Why would we've any reason to believe Russia would honor such an agreement now?โ
Chances are considered a bit better, if still a long shot, that both leaders might agree to a โvoluntary non-binding commitmentโ to lower their number of deployed strategic nuclear weapons to 1,400 this year, such as the long-range missiles in underground silos, aboard submarines or outfitted on bomber aircraft.
Both countries have already declared under the reporting requirements of New START that they are well below the limit of 1,550. Agreeing to keep to a lower level โshould be feasible and would be symbolically important,โ the ex-American, European and Russian officials argued the previous week.
Biden and Putin are also being encouraged to use their Geneva meeting to reaffirm the joint statement made at the height of the Cold War in 1986 by then-Presidents Ronald Reagan and Mikhail Gorbachev that โa nuclear war can't be won and must never be fought.โ
Advocates contend that such a declaration would send a strong signal of a collective commitment to ratchet down the nuclear rivalry.
Morrison said โI wouldnโt be surprisedโ if that happens, though he said the Trump administration opted against such a statement without some commitment from Russia that it's actually reducing the role of nuclear weapons in its military planning.
Whatโs clear is that U.S allies in Europe are banking on at least some modest breakthrough on the nuclear front.
Germanyโs foreign minister, Heiko Maas, told the German parliament the previous week that he has conveyed to the Americans his hope that nuclear disarmament will be at the top of the Biden-Putin agenda.
Still, the relationship is so fragile that any new confrontation, such as another cyber attack traced to Moscow or more military action in Ukraine, could derail nuclear talks before they even get going.
โThe extent to which you can isolate arms control from everything else is a big question,โ said Sokov. โIt's a delicate balancing act. If the balance is off, everything begins to crumble.โ
