You raise a good point re #4 but I divide the argument really into two pieces.
1) Judgment calls which are very hard to make and often the other side can fool you. Like Hamas is now peaceful or that this threat sound no different than the rest etc. or that exercise son the border are their classic games.
2) Planning in advance so that we are prepped if an event occurs. Its under this category where you need to blame senior leaders. There is no excuse no to plan a defense for the worse.
