Hendrix was a former paratrooper and, from I understand, was not opposed to the Vietnam War.
There was some leftist fantasy movie of that era which centered around a rock group known as Max Storm and the Troopers who were using a slogan "14 or fight" to expand the franchise to include all 14 and older and particularly the gummint edjumacated and brainlaundered liberals among them to speed the transfer of power to their adored celebrities. They got the Senate to vote a constitutional amendment by pouring LSD into the DC water system and physically holding up the arms of tripping Senators to approve their amendment. It has always been a fantasy of the left ever since that the necessary revolution will consist of attending entertaining rock concerts, smoking dope, copping cheap feels and yelling and screaming that will show THEM (us) who is REALLY the boss from now on!!!!
