The point is to distinguish this war from how others have been fought. A lot of accusations against the IDF's conduct have been baseless. Not wrong in that they're factually incorrect. Just wrong in that it's how everyone else fights wars when they go to war.
This is different. America didn't trigger a famine in Iraq or Afghanistan, and it's not like we fought those wars honorably. That is where it's worth answering the question, is this just war or is this worse.
