That's obviously a misrepresentation of the opposing point of view, whether you agree with it or not. It's more like "Imposing a ceasefire prevents Israel from retaliating against Hamas killing 1200 civilians".
I wouldn't call it a misrepresentation. That's the form of retaliation they've decided to take, so if you are of the opinion that preventing Israel from seeking that retaliation is bad, you have to be fine with indiscriminate bombing of civilians.
What is this medieval Europe? So the argument against a ceasefire is to just keep bombing, killing, rounding up people, destroying buildings and basically bombing everything to nothing is the answer.
It's not just for Israel ... it's a showcase for the world ... if Israel can get away with conducting a war in whatever way they please, what is to stop others from doing the same? Without rule of international law equally applied to everyone ... what's to stop others from starting the same thing?
If the war and killing and bombing just continues unabated ... then we are no better than our ancestors a thousand years ago. We may have progressed technologically but we've hardly evolved from our war like, fearful, and short sighted ancient mentality.
