On the morning of October 7, 2023, Hamas began rocket fire on Israel - firing from 2.5 to 5 thousand missiles, 2.5 thousand militants entered the country. As a result, 1.4 thousand Israelis were killed, 3.3 thousand were injured, 220 were hijacked to the Gaza Strip as hostages. The next day, the Israeli government announced the transition of the country "to a state of war." According to the unanimous opinion of Israeli and Western politicians and experts: the Hamas attack is the largest defeat of the Israeli special services, which is comparable to the terrorist attack on September 11, 2001. Why was Israel's legendary security system, on which billions were spent, powerless in front of the paramilitary forces of one of the poorest enclaves in the world - the Gaza Strip? Why did AMAN military intelligence and Israel's Shabak Internal Security Service (Shin Bet) lose to Hamas and what did the legendary Mossad do? This and many other things were first described in this book.
