PODS: a million flies in the middle of Africa dies. Those bugs had no effect anywhere, so do not change history at all. There, 1000000 PODs with OTL result.
But seriously, if you believe in the butterfly effect, any changes means not OTL modern times.
There is a predisposition on this forum to believe in the butterfly effect, because its more fun. The other school of thought being the broader course of history is very difficult to change, no matter how many changes you make.
Take Communism for example, massive POD to create new politics, ideas, and culture. In the end most Communist countries reverted to pre-Communist systems. Butterflies may cause tornadoes, but they can't change the human condition.
