> Yep, if Russia wants to expand its conflict against Europe, Narva in Estonia is most likely place for it. Over 90% of its population is ethnic Russian, and it's located right next to the Russian border. It's the perfect place to send some armed "separatists" to see how NATO responds.

Fortunately while close, the border runs along a fairly wide river with just a single bridge across, so logistically somewhat complicated to supply with heavy equipment from the Russian side. At least covertly.

But definitely a scenario that needs to be considered.

Little green men. Crimea is an island.
