"terror tunnels designed to murder and kidnap Israelis and store weapons"
The tunnels were designed for no such reason, they were built to transport essential good that were forbidden by the blockade; many of them became profitable enterprises for those on both sides of the border.   

That is shite Jim.
It may have been partly true of the tunnels into Egypt, but even they had to be closed because they were used to attack Egypt.
The tunnels into Israel are not for smuggling.
They are just for attack.
