Russia-US relations Illustration: Liu Rui/GT

As the recent expulsions of Russian diplomats from the US, Poland, Bulgaria and the Czech Republic demonstrate, this measure is becoming a standard international practice of the West. For the Biden administration, a new manifestation of the "Russia's threat" is an additional tool to discipline its European allies and to cement the transatlantic partnership. For many European NATO members, expulsions of diplomats are a symbolic gesture demonstrating their firm support of the US and its anti-Russian policies.

Clear enough, such a practice will not be limited to Russia only. Today hundreds, if not thousands of diplomatic officers all around the world find themselves hostage to problems they have nothing to do with. Western decision-makers seem to consider hosting foreign diplomats not as something natural and uncontroversial but rather as a sort of privilege temporarily granted to a particular country — one that can be denied at any given moment.

It would be logical to assume that in times of crisis, when the cost of any error grows exponentially, it is particularly crucial to preserve and even to expand the existing diplomatic channels. Each diplomat, irrespective of his or her rank and post, is, inter alia, a communications channel, a source of information, and a party to a dialogue that can help understand your opponent's logic, fears, intentions, and expectations. Niccolo Machiavelli's adage, "Keep your friends close and your enemies closer" remains just as pertinent five centuries later. Unfortunately, these wise words are out of circulation in most Western capitals today.

A proponent of expulsions would argue that those expelled are not actually diplomats at all. They are alleged intelligence officers and their mission is to undermine the host country's national security. Therefore, expulsions are justified and appropriate. However, this logic appears to be extremely dubious. Indeed, if you have hard evidence, or at the very least a reasonable suspicion that a diplomatic mission serves as a front office for intelligence officers, and if operations of these officers are causing serious harm to your country's security, why should you wait for the latest political crisis to expel them? You should not tolerate their presence in principle and expel them once you expose them.  

Even the experience of the Cold War itself demonstrates that expulsions of diplomats produce no short-term or long-term positive results whatsoever. In fact, there can be no possible positive results because diplomatic service is nothing more but just one of a number of technical instruments used in foreign politics. Diplomats may bring you bad messages from their capitals and they often do, but if you are smart enough, you never shoot the messenger.    

Diplomatic traditions do not allow such unfriendly actions to go unnoticed. Moscow has to respond. Usually, states respond to expulsions of their diplomats by symmetrical actions - i.e. Russia has to expel the same number of US, Polish or Czech diplomats, as the number of Russian diplomats expelled from the US, Poland or the Czech Republic. Of course, each case is special. For instance, the Czech Embassy in Moscow is much smaller than the Russian Embassy in Prague, so the impact of the symmetrical actions on the Czech diplomatic mission in Russia will be quite strong.

The question now is whether the Kremlin would go beyond a symmetrical response and start a new cycle of escalation. For example, it could set new restrictions upon Western companies operating in the country, it could cancel accreditation of select Western media in Moscow, it could close branches of US and European foundations and NGOs in Russia. I hope that the final response will be measured and not excessive.

The door for US-Russian negotiations is still open. So far, both sides tried to avoid specific actions that would make these negotiations absolutely impossible. The recent US sanctions against Russia have been mostly symbolic, and the Russian leadership so far has demonstrated no appetite for a rapid further escalation. I think that a meeting between Presidents Joe Biden and Vladimir Putin remains an option and an opportunity. Such a meeting would not lead to any "reset" in the bilateral relations, but it would bring more clarity to the relationship. To stabilize US-Russian relations even at a very low level would already be a major accomplishment.
