Israel did indeed shut down Kerem Shalom in order to protect the lives of the people that work there. And anyone could understand if would have shrugged and said it is no longer their problem to provide aid to people so dedicated to hate and addicted to death. There's only so much one can do to help your enemy, right? Let Egypt, Hamas' friend, take care of that.
Yet the IDF did manage to get aid through. As COGAT notes:
This afternoon (Wednesday) 5 trucks carrying medical equipment entered Gaza via the Erez crossing.This was during some of the heaviest rocket barrages of the conflict.
The Erez crossing is not built for major truck deliveries, but Israel went out of its way anyway in order to allow the aid to get to Gaza however it could.
Has this ever happened in the history of wartime? (Besides, of course, the daily cease-fires during Cast Lead - which Hamas never respected - in order for Israel to send food and aid to Gaza.)
Egypt, Gaza's friend, was pretending to send in token medical aid along with lots of human shields and wannabe jihadists.
Anyone who actually thinks that Israel's morality is somehow comparable to - or worse than - that of its neighbors, doesn't even have a passing relationship with reality.
