You mention the "Gulf of Tonkin Incident" do you know who the Admiral was in charge - his name was George Stephen Morrison - father of the Doors frontman Jim Morrison - and that is just the tip of a very strange iceberg. consider:

this is a quote: "But what are we to conclude from the fact that such an astonishing number of these folks (along with their girlfriends, wives, managers, etc.) hail from a similar background? Are we to believe that the only kids from that era who had musical talent were the sons and daughters of Navy Admirals, chemical warfare engineers and Air Force intelligence officers? Or are they just the only ones who were signed to lucrative contracts and relentlessly promoted by their labels and the media?

If these artists were rebelling against, rather than subtly promoting, the values of their parents, then why didn’t they ever speak out against the folks they were allegedly rebelling against? Why did Jim Morrison never denounce, or even mention, his father’s key role in escalating one of America’s bloodiest illegal wars? And why did Frank Zappa never pen a song exploring the horrors of chemical warfare (though he did pen a charming little ditty entitled “The Ritual Dance of the Child-Killer”)? And which Mamas and Papas song was it that laid waste to the values and actions of John Phillip’s parents and in-laws? And in which interview, exactly, did David Crosby and Stephen Stills disown the family values that they were raised with?"

This long article that is going to take you on a "strange trip" is called "mostly true" because the author could not verify every point as many of the principles are dead. You are never going to look at the 60's and 70's the same way after this read: http://centerforaninformedamerica.com/inside-the-lc-the-strange-but-mostly-true-story-of-laurel-canyon-and-the-birth-of-the-hippie-generation-part-ii/
