So Russian fighter jets violated Estonia’s airspace this week for 12 minutes, and Estonia seems to be one of the only countries in Europe taking the Russian threat seriously. Recently I went to Estonia to interview volunteers, drone units, and civilians to find out how they’re preparing for Russia’s new front line.

Putin has openly said he wants the Baltics. His propagandists have said the same. So now Estonia is digging trenches, fortifying its border, closing bridges, and mobilizing its population, ready for the worst case scenario.
