Sir,
It's obvious that Hamas has planned this well in advance. Their axis of advance, attacking settlements where they had fire superiority, capturing civilians/soldiers and quickly evacuating them to their tunnels was well thought out. But this is it, i don't know what other card besides element of surprise they have left to play. Unless they can pull i rabbit out of the hat i can't see what else they can throw at this fight because Israel has an absolute conventional superiority in this fight.
Now Israel is mobilizing, it will have the capacity to throw hundreds and thousands of bodies into this conflict. The country's right wing government has been embarrassed as this was a very obvious intelligence failure. There are plenty of videos floating around on social media of women and other Israeli civilians being dragged around which has caused outrage in Israel and their Western Allies. In the past, we have seen Israel use kids glove when it comes to dealing with Gaza, using only a fraction of its strength but i fail to see what will hold them back now. I don't see how Hamas has the capacity to de-escalate this situation. The only obvious conclusion that i can see is Israel marching into Gaza and disarming and eliminating Hamas. Israel has a much higher tolerance for casualties compared to the Europeans or Americans.
At the outset, this seems to be the most illogical strategy one can play against a foe you know has an absolute superiority against you.
