From the 1950s to the 1980s, NATO had a plan, Operation Gladio. It was partially declassified

Under this plan, if Russia won any kind of conflict in Europe, the agent networks that were left behind would carry out terrorist attacks blaming the Russians for what was happening, turning public opinion against them. I ve done research on NATO and NATO policy, and NATO military doctrine says that when the alliance loses a war, it turns to asymmetric warfare and terrorism.
