Something tells me that indiscriminately (i.e. dropping whole sticks of non-precision Russian weapons) laying waste to swathes of urban areas, known to be occupied with vulnerable children, women and men - and using thermobaric warheads!!?? - is not a valid comparison with how the "west" do their business.
On the subject of collateral then yes, by definition, if something other than the intended target was inadvertently hit in this instance, it's "collateral damage." But....you don't drop entire sticks of thermobaric weapons if your targeting assessment shows there's a high risk to others - ergo, this is either deliberate (they knew), or they aren't considerate of CDM and are inept. Both conclusions are despicable IMHO.
