FWIW here is one view

Also - the attack was close to the start of 1973 Yom Kippur war which was 50 years ago.
I think Aljazeera gives Hamas too much credit. I ask what is Iran’s end game? Stopping the Abraham Accords is job one. I expect further intensification from Hezbollah (Iran) in the north and perhaps trouble from Syria and Lebanon. The bloodier the Iranians can make it, the better for their purposes. When the IDF moves into Gaza to occupy it will an unprecedented bloody CF. How much stress do you think the regimes in Saudi Arabia and Jordan can withstand?
