Simply raising possibilities, John. It's possible that any of those people could have acted alone. It's also possible that one or another of them did not act alone. An assassination is far more likely to succeed, I think, when it is planned and carried out by well-trained professionals. Read the Rolling Stone article that the link was provided to awhile back in this thread...the interview with E. Howard Hunt's son...it's very interesting.

Number 6 - Not only in every religion, but in every positive philosophy known to man is embodied that same principle...that perseverance is the key to success. It's just common sense. Accordingly, it is found in all religions.

"God helps those who help themselves" is a common way of putting it. Every religion and every positive philosophy attempt to instill in people attitudes of perseverance, steadfastness, and determination.

Matter of fact, even the most vicious and negative philosophies have attempted to instill that attitude in their followers. Hitler, for instance, was big on the concept of perseverance...even to the point of being totally unrealistic about it when declining military situations for the Germans had passed way beyond any hope of recovery.

And so were Stalin and FDR and Tojo and Churchill and Patton big on perseverance. Hell, they all were... ;-)

Nixon: "When the going gets tough, the tough get going."

It's clearly a sentiment that can be used, as most strong sentiments can, for both good and evil purposes....keeping in mind that everyone always seems to think that HIS purposes are among the good ones... ;-) It's a universal conceit.
