Hawkins himself writes:
You need to read the August 2006 newsletter again. The House of Yahweh is not wrong on these prophecies. This thirteen months, which started September 12, 2006, is the starting point for nuclear wars that will kill a third part of man over a fourth part of the earth in and around the great river Euphrates but it will not stop there.
In other words, he says he never said that there would be, like, nuclear bombs and stuff going off on Sep. 12, just that it would be the beginning of a 13-month “tribulation” that would include a nuclear war. So, for instance, this blurb on his web page:
The Days After September 12, 2006
The days following September 12, 2006 will be filled with fear of reprisal and more nuclear destruction.
was never intended to say that there would be nuclear destruction on Sep. 12. Right.
