I'm glad you brought this up. From the first BREXIT rumors to the present, we have (here and abroad) entirely failed to give Russians credit for the immense damage they've done to democracy everywhere.
While there is no way to know the exact degree of damage done by the Internet Research Agency in St. Petersburg, we do know their focus was undermining democratic institutions. Yet few in Britain want to acknowledge that they were largely swayed by anti-immigration, nationalistic drivel, created and disseminated by Russians, at the direction of Putin.
