The thread isn't about 186,000 Gazans having been killed, though.
The published piece is saying that it's not implausible that the death toll of the conflict could reach that figure. Some of the estimates they've used are actually at the conservative end of calculations.
Looking at modelling or estimates of 6-figure death tolls as part of the cost of a conflict really should prompt reflection and consideration of whether enough is being done to mitigate those harms and prevent those deaths. We currently live in a world where there are several horrendous conflicts, where similar death tolls could be part of the cost. Are we satisfied that there are no alternatives? That nothing else could be done? Is this cost a price we think is worth paying?
There are things that could be done today, to try to avoid that potential outcome. Rather than seeking to dismiss or distract from a sobering reminder of part of what is at stake here, maybe we should be thinking about whether there is anything we can do to try to reduce the chances of these estimates becoming reality.
