Due to Mossad Intelligence being excellent, they probably have listening devices in other items. Soldiers should probably check the the new water kettles in their underground locations, check the bottom of their newly issued shoes, check their hair preparation for nanites that transmit information, etc.
I suspect these transmitting devices are why Netanyahu knows they will have the bomb in six months or less.
Agreed - when they ‘go’, we’ll know that it was time. And nobody screws with Mossad.
