@SW-User Yes, Oct 7, or the result of Hamas' attack was in part due to a failure of Israel. Nonetheless, they did stage and carry out a brutal act of aggression/war against Israel.
An attack supported by Iran, the major source of weaponry and materials which are what allows the very existence of Hamas.
Iran has vowed to destroy Israel and supports terrorism throughout the Middle East and the world.
They, not Israel, risk the security of the world.
No country can, with enemies surrounding them, can ever maintain 24/7/365 security endlessly. There will be failures, breaches, lapses, etc. Evidence Ukraine's incursion into Russia, a county with tenfold their military might.
The real question, at least for me, is why should the world allow Iran to endanger our world. Enough is enough.
