This loss of innocent life would not have happened if Israel had not been defending its 'counterproductive and unacceptable blockade' as UN spokesmen put it, which penalizes innocent women and children, causing immense human suffering.
It would not have happened if Israel abided by international human rights law, which it does not.
It would not have happened if Israel was obedient to the Law of God. Read, for example, Psalm 146, vv 5-7
"How blessed is he whose help is the God of Jacob, whose hope is in the LORD his God,
Who made heaven and earth, the sea and all that is in them; who keeps faith forever;
Who executes justice for the oppressed; who gives food to the hungry. The LORD sets the prisoners free."
Israelis are fond of saying that they have the land because of the promise of God to Abraham. Anyone who reads Moses or the prophets can see that this promise is conditional on obedience to the law. It was for disobedience that Israel lost the land before. They do not appear to have changed their ways.
