Containing The Putin Syndicate

The signs of the times are everywhere.

Estonia is erecting a 2.5-meter-high metal mesh fence reinforced with barbed wire along much of its border with Russia -- and backing it up with high-tech drones, sensors, radars, and cameras.

Neighboring Latvia has also announced plans to build fences along its eastern frontier. Poland plans to build new state-of-the art watchtowers on its border with Russia's Kaliningrad exclave.

And, of course, Ukraine has floated plans to build a wall along its Russian frontier.

A new era of containment, it appears, has begun.

Russia's neighbors, wary of polite little green men appearing to stir up new nondeclared hybrid wars, are building walls and becoming vigilant.
