Your post has reinforced my view that a coloniser can only enforce their presence by brutal force.
You speak of the brutality of 7/10 and the need to destroy tunnels and explosives. However- you fail to mention the devastation that Israel has wreaked in Gaza and that their safety comes at the expense of innocent people including thousands of children.
Does it make Israel feel safer to have caused this?
They may have neutralised an immediate threat from Gaza, but look what is happening on it’s northern border. See what’s happening to its trade routes with the Houthis bombing ships on route to Israel. They have agitated many people against their cause. And I do want Israel to exist, but not by inflicting plausible genocide.
So - no, I can’t see that this has made Israel a safer place in the short, medium or long term.
I think Israelis feel the same given concerns about immigration/ emigration from the country.
