 I would say 15,000 would mean in and around half of that fighting force. Those are the ones that were mainly active and, of course, participated not just in the October 7th attack, but in all of the subsequent fighting that's been going on in the last nine months. How was Hamas able to construct these hundreds of miles of concrete tunnels that you're talking about without Israel knowing that was happening? I mean, this has been a question since the beginning of this conflict, but doesn't that suggest a real lapse of intelligence?
