Most of your post is just angry hyperbole. Can you provide evidence directly linking JFK to the assassinations or is this just your conspiracy theory. You sound like a neocon partisan hack. .
Not sure how adhering to a political philosophy forty years removed from the events being discussed is a relevant charge. Kennedy's administration was fully aware of the coup that led to the assassination. My original assertion: that Kennedy, along with all other Presidents during the Vietnam era, made decisions that indisputably worsened the situation, still stands.

Government was so cute back then, everyone concerned that people would know they were invading people's privacy. Bless their hearts.
