Chaos means that a small change in initial conditions can lead to drastically different places in the long term

Yes, what I was trying to explain is that it could (no closed form) but doesn’t necessarily mean that is must. A chain with 2 segments is a double pendulum, the classic simple chaotic system. If you hold a piece of chain and give it a light tap, it will move chaotically for a few seconds and then come back to rest. The system will not have changed. Even with a hard push, the chain can’t move beyond the limit of the links.

If you gave Hitler’s dad a push, he would stumble for a second (chaotically), then go back to walking (return to initial state). Nothing would change.
