Thanks Wei. You efforts here is much appreciated and your place in heaven is assured.

In reply to your 5.

My suspicion is not based on any significant evidence. It's just a thought that emerged in my head as I've followed the story. It's a psychological thing, almost macho - people like to solve a problem that nobody else has been able to prove something to themselves (and others).

Also from his comment 'we can win a major battle in the arms race and gain a new territory of freedom for several years' I infer that he didn't think it would last foreever .

Anyway THANK YOU WEI for taking the time to do this.
