disproportionality of Israel's response

Because there were few Jews killed by the rockets?
Only because a third of the population were living in shelters!
A school was hit (again).
No children died because instead of being at school with their friends they were huddled, terrified, underground and had been for weeks.
Businesses and services shut down.
That is not acceptable, and the absence of many actual dead Jews does not make it OK.
The response was intended to stop the rockets, but it only reduced them, so not that disproportionate.
