Yes it has.
It has also been shaped by non-violent methods, e.g., one of the biggest being the fall of Communism, which was done without wars and those without power in: Poland (Solidarity); the Baltic countries (Singing revolution); Lithuania, Latvia and Estonia (Baltic Way); Czechoslovakia (Velvet Revolution).
It was done in the Philippines (People Power Revolution), etc.
That said, I believe you are tackling some highly complex topics here. Have you explored well-researched studies, such as “The Strategic Defense Initiative and the End of the Cold War” [1]?
There are a lot of folks in this discussion—many of whom I suspect are Americans and may have a particular (historical) view of how to gain "freedom"—who seem to jump to the 'violent struggle' path. I'm simply pointing out references that support the possibility that is not the only path, and other ones may actually be better, especially in more recent decades (as opposed to what happened hundred-plus years ago).
The world has been shaped by power and wars, an undeniable fact that stands without the need for statistical gymnastics.
