A few thoughts...
1. At the end of the day, we (the public, at least) don't really have much granular data on casualties and deaths, including whether the approaching 30k number is accurate in the aggregate (I suspect understated), what the mix of civilians and irregulars (I hesitate to call them soldiers) is, how the death rate has changed over time, or how they died.
2. I continue to believe that in a densely populated area of 2.5 million or so, 30k total casualties is not a shock the conscience number given the nature and scope of the Israeli response, and if anything, creates more of an inference of care than recklessness. (That assumes, of course, that you have a conscience that is willing to set aside, for the sake of argument, the general immorality yet occasional necessity of war.) And indeed some of that has been borne out quite literally with announced evacuation routes, such as they are.
3. From the little that I've seen, it would appear that the bulk of deaths occurred in the first half of the Israeli response, and that things have slowed down a bit since then (with obvious spikes as new territorial thrusts began). Again, the better inference here would seem to be relatively focused rather than indiscriminate activity.
4. One can always quibble about what the 'appropriate' ratio of civilian collateral damage should be in the aggregate numbers. But to me, the images that we see of coordinated and conscious hamas infrastructure, which in turn led to initial response using missiles and artillery, suggest that ratio might be higher than, say, a target sniper response or some of the on or under the ground clearing operations going on now.
At the end of the day, it's war, and it sucks. But perhaps we 21st century types ought to rethink our unwillingness to have one side actually win a war on occasion when they break out, rather than perpetuating grievances across generations.
