I would really love to see no more civilians, adults or children, die in this war.
I don't know what would be more effective with that goal in mind. I would think that a ground invasion, going house to house might be less destructive of civilians, but I don't know that.
There are conflicting stories.... the Palestinians were told to leave, then Hamas prevented them from doing so. Some say the Israelis prevented them from doing so.
Either way, when an army is trying to root out the enemy, and the enemy hides behind civilians, it's almost impossible to prevent civilian casualties.
I suppose Israel could just back off and do nothing, but Hamas is still firing rockets into Israel, targeting civilians.... should they just suck it up and allow that to continue?
