Seven decades after George Kennan's famous essay, The Sources Of Soviet Conduct, laid the groundwork for the U.S. Cold War policy of containment, a new policy of containment is beginning to take shape in Europe.
And Russia's neighbors and Moscow's former vassal states in Eastern Europe are leading the way.
Which isn't surprising. They know best how the Kremlin operates, after all.
Vladimir Putin's regime has long been waging a shadowy, nonkinetic war on its neighbors and on the West.
It has weaponized business, finance, corruption, organized crime, religion, cyberspace, and information as part of a concerted effort to undermine Western institutions.
And containing this threat requires some outside-the-box thinking.
This is not just a job for defense ministries and intelligence services.
It requires a whole-of-government approach, including law enforcement and regulatory agencies.
Russia's 21st-century, nonkinetic political war on the West requires a 21st-century, nonkinetic form of containment.
Russia's neighbors get this. And we can all learn a lot from them.
