There was something obscenely ironic about Kremlin officials and surrogates cheering the results of the Brexit referendum, given that a similar democratic exercise could never take place in Vladimir Putin's Russia.
But while it was ironic to see the likes of Dmitry Kiselyov, Aleksei Pushkov, and Vladimir Zhirinovsky singing the praises of British voters exercising their democratic rights, it's not surprising at all.
The Kremlin has become very skilled at using Europe's democratic institutions -- like free-and-fair elections, the free press, and freedom of speech and assembly -- to undermine and divide the EU.
It cheers on and supports xenophobic and Euroskeptic figures like France's Marine Le Pen and Britain's Nigel Farage, turning every election in Europe into a potential crisis.
It uses stealthily funded pro-Kremlin media to sow doubt, confusion, division, Euroskepticism, and anti-Americanism across the continent.
And it manufactures crises and stages rent-a-crowd protests, like the infamous Lisa case in Germany, to undermine Europeans' faith in their leaders.
And any move to counter these moves, such as Lithuania's ban on certain Russian media for inciting hatred, are met with accusations that Europe is violating basic freedoms.
And, of course, the Kremlin is doing all this even as it has eliminated those freedoms in Russia itself.
It's asymmetrical warfare on a grand scale, it's been going on for awhile, and it's not going to stop anytime soon.
