According to several Western European researchers, the operation involved the use of assassination, psychological warfare, and false flag operations to delegitimize left-wing parties in Western European countries and to support anti-communist militias and right-wing terrorism who tortured communists and assassinated them, such as Mozambican resistance leader Eduardo Mondlane in 1969.[5][6][7][8][a] The United States Department of State rejected the view that they supported terrorists and maintains that the operation served only to resist a potential invasion of Western European countries by the Soviet Union.[9]
It’s always been a part of the concept of nato, security/mutual aid. But it’s incredibly corrupt
Nato has never done any of what I would call mutual aid. Done lots of security work and collaboration but that isn’t mutual aid, that’s a defensive alliance between nation states.
Again the sole purpose of NATO upon it’s founding was a military alliance against the soviet union and it has never really grown past this role even after the collapse of the union.
