No expensive war machines were used. You don't see airplanes dropping bombs but angry people throwing stones only. How cheap is a stone? It costs nothing, however, it is powerful enough to throw away leaders. It needs no big money to replace them.
It could turn a whole country up-side-down. Busy leaders won't have a time to think about this. Most of them were above the ground, they could only see figures and read fake reports. They won't have the real scenario in their mind. They didn't know thoughts are changeable.
