Quayle just connected a dot on the GPS inactivation. He believes that some of the cruise missiles fired by Clinton did not detonate. They were captured and handed to China for re-configuration. Quayle believes China has re-armed them and passed them back to al Qaeda. Our cruise missiles use GPS on a pre-loaded program to traverse from launch to target. Disabling GPS over the east coast on demand would make a pretty hard to launch a cruise missile from a distance without being detected and navigationally disabled.
Quayle also opines that China completed work on the neutron bomb and has passed it to Iran. Iran has threatened to nail 29 "sensitive" locations if their nuclear facilities are threatened.
