No, it's really not necessarily what it looks like at all, though you could be forgiven for thinking it. I think perhaps this is the difference between those who focus on this issue because they're interested in Israel, versus those who focus on it mainly because they're interested in human rights.
You could blindly drop a bomb quite literally anywhere
Blindly dropping bombs on densely populated areas is a war crime.
Yes, killing this many people this fast is a consequence of the choices the IDF is making. No, they are not inevitable choices.
For instance, in its entire war against Islamic State the US dropped just one 2,000lb bomb. Israel is dropping hundreds of them.
Roof knocking and leaflets are a fig leaf - a fiction with the aim of avoiding international condemnation, a bit like the peculiar interpretations of "occupying force" and international law we see from them.
I've seen footage of those leaflets raining down on innocent people in Gaza, the panic and despair. It's not humanitarian at all. Ironically some of the people best equipped to get away in time are Hamas fighters, which is probably why the IDF uses "Where's Daddy" to kill suspected Hamas leaders when they are at home.
continue with their plan
Israeli politicians and public figures have been pretty clear in their national discourse about what their plans are. I don't think we need to speculate further than that.
