In the two years since Russia made headlines for targeting an American political organization – the Democratic National Committee – and undermining Hillary Clinton’s race for the presidency, Russian information warfare tactics have come a long way. That includes using more subtle means of hiding their traces. Recently, Microsoft announced that it had detected Russians targeting conservative think tanks.

The Russians are not just aiming to influence political activities in the U.S. Rather, it’s extremely likely that they will soon target American civic society. They’re the local sports teams, charities, Kiwanis and Lions clubs, churches and even community groups like the Boy Scouts. Those are the groups that knit together a community and a society, providing connections that keep legitimate disagreement from exploding into acrimony and sharp divisions.

It may be hard to imagine Russia going after the Boy Scouts. But consider how Russia is seeking to sow social disconnection and mistrust in Europe. The Kremlin uses disinformation campaigns and other disruptive tools to “sow discord among European Union member states [and] destabilize European polities,” according to a 2016 Atlantic Council report. For instance, a deliberately false news story planted by the Russian government claiming that an Arab migrant had raped a Russian-German teenager exacerbated tensions over Germany’s immigration policies.

Russia is trying to create similar social tension in the U.S. – because an America that is tearing itself apart will be unable to contest Russia internationally.

Russian attacks on civil society

Russian efforts go well beyond interference in the 2016 presidential election. The State Department has documented Russian efforts “focus[ed] on exploiting internal discord in an effort to break centrist consensus on the importance of core institutions.”

Russian-operated accounts have masqueraded as Americans, setting up demonstrations about hot-button issues, including rallies protesting racism and a demonstration against a planned Islamic center in Houston.

Most recently, Russian attackers set up fake websites for the Hudson Institute and the International Republican Institute, two conservative think tanks seeking to counter Russian export of corrupt practices to the West. The sites were designed to collect login credentials that could be used to publish false, misleading or damaging information that appeared to come from official sources.

A similar technique appears to have been used against Texas Democrat Beto O'Rourke’s Senate campaign, in which text messages purporting to be from inside his campaign offered to transport undocumented voters to the polls. The texts were from the campaign – but from a first-time “volunteer” who had signed up under a fake identity. O'Rourke’s campaign quickly disavowed the texts, but the bad taste they created won’t fade as fast. There’s no indication this specific incident was Russian-made, but the example illustrates the type of activity they use to create discord.

The role of social media

Social media gives Russians – and any other adversaries – a perfect tool to foment civic disruption. First, attackers can claim to be in, or from, the U.S., deceiving other users about aspects of their identities. In addition, social media has been designed to be addictive; pulling people toward more extreme views helps keep them hooked. As people are exposed to these views, and their social community shifts, they may find their views changing as well.

In Germany, for instance, a town whose residents used Facebook a lot started out embracing refugees: “So many locals volunteered to help” that the refugee integration center was almost overwhelmed. But then came a rise in hate crimes against the newcomers – while towns whose people used Facebook less saw smaller increases in violence.

What about the Boy Scouts?

In the U.S., the Boy Scouts could be a tempting target for Russians seeking to inflame social discord. Over the past 50 years, the organization has been embroiled in various controversies over social values. The organization has internally – and publicly – debated allowing women to serve in leadership roles, whether to let gay men and boys join and lead scout troops, whether transgender boys could join and, most recently, including girls in Cub Scout and Boy Scout groups.

All of those changes, raising legitimate questions about equality and humanity, involved heated discussions in the scouting community and the wider society. Now imagine that an outside group – one whose only goal was discord – jumped in to deliberately inflame the debate.

Protecting society as a whole

The Russians are coming for American society. They’ve attacked national organizations; it’s only a matter of time until they go after the less protected local groups.

People need better ways to resist the attacks. Technical protections can help. Individuals can improve their cybersecurity, opting for stronger login requirements. Internet companies can develop tools that quickly identify fake accounts and better vet clients to prevent promotions of phony content. But technology can only do so much. Defense is social, not technical.

The Nordic countries – Denmark, Finland, Norway, Sweden – have had great success combating the Russian efforts. Their defenses include knowing their enemy better, education systems that emphasize critical thinking and new efforts to teach ways to differentiate between reliable and unreliable sources and actively counter the Russian efforts.

The U.S. is starting from a different, more divided, place, and its solutions must compensate for the inherent differences of the country’s big melting pot. Given the Russian efforts at disinformation and sowing mistrust, it’s time for Americans to change their behavior.

I suggest taking sharp political disagreements offline. That may sound like a step back to the 1990s, but there’s little choice. Social media is great for sharing photos of friends and family. But for anything controversial, including political discussions and civic issues, the technology creates an unequal playing field, making extremism and outrage easier than reason and calm. With adversaries attacking in force, Americans should be responding strongly to protect themselves. What’s at stake is the very society we share.
