Interesting article, Lion---I even found some humor in it:
U.N. inspectors suspected a vast network tunnel but never proved it.
The UN is irrelevant and incompetent.
Our military needs to be careful when they go down those tunnels, as I'm sure many are booby-trapped. They should send in robotic equipment and birds before sending in humans.
I know we are at least working on robots to go into tunnels and places where no man dares to go. The cool thing is that they can also be rigged to explode on command....our own brand of suicide bomber. They could give them a voice like #5 in the movie and a sense of humor..."What's up Doc"....Boom! Woody Woodpecker would be my favorite.
