Sorry, what were those reasons?
You've asserted that there exists a small chance Hamad will destroy Israel, and Hamas is committed to continuing to try to destroy Israel, therefor Hamas will eventually succeed, therefore Hamas poses an existential threat.
Me and my golden retrievers have a small chance of success, and we will keep trying, and therefore we will eventually succeed (according to your moronic logic) and therefore we pose an existential threat to China (by your moronic logic).
