Israeli Tanks move into Gaza
Briefly; this won’t work. Deploying a mechanised block designed solely for slaughter in a neighbourhood alienates everyone in the neighbourhood. Even if you have a specific target, it looks as though you threaten everyone, because it’s so loud and intimidating.
Most Gazans will thus perceive themselves as under threat. They will turn to those who offer to protect them; here, Hamas.
Hamas will then have yet more fleshy fodder to throw into a vicious ground war with the IDF. This will be particularly bloody, given the degree to which Gaza resembles a warren designed for guerilla fighting. A long and ugly struggle will follow.
This could end in a very few ways. The ground war could go on and on and on and be reduced to a a stagnant quagmire. The IDF could slaughter so many Gazans that any will to resist is sapped and the strip is annexed; violence inevitably follows from the West Bank. Or the IDF could suffer a setback, withdraw, and the old stand-off could resume.
None of these will help anyone involved.
“the IDF could suffer a setback, withdraw”
That would help everyone but it won’t happen
“the IDF could slaughter so many Gazans that any will to resist is sapped”
That appears to be what Israel is after: kill Palestinians until Palestinians lose the will to kill. Hasn’t worked in 60 years, it won’t work now
