>the IDF put Israeli soldiers lives on the line to avoid civilian casualties.

Ah, I get it, you're talking about Israeli casualties, not innocent Palestinian children civilians.

They do need to put boots on the ground (which they've already carpet bombed), they do need to send warnings to the innocent people they are about to murder.

For the PR, which is necessary to the purpose of ethnically cleansing Gaza, unimpeded by the rest of the worlds' moral compass.
