bluzman61 the main reason he was killed is because he was going to pull out of Vietnam.released documents from the ninetys confirmed what many researchers suspected but never had proof till then at was the case,they only had two of his top aides who he confided to that he would pull out after getting re-elected that he had to wait till his second term to do so.
He never sent in combat troops,LBJ did.he only sent in advisors,even the msm media admits that.kennedy had signed an executive order two days prior to his assassination thst called for a complete withdrawel from Vietnam by 1965, that can’t be debated anymore,the documents got released in the late 90’s confirming thst which breaks the hearts of the oswald lone gunman theorists

Once lbj got in he reversed Kennedy’s policys of withdrawel and expanded the war,the elite knew lbj would give them the war they wanted.he was also going to get rid of the fed,lbj reversed that course as well.
