The way I understand it, the provocation to justify increased US involvement was staged for political purposes to get support from the US public, but the Vietnamese were fighting for independence from the French before the US got involved. They asked the US for assistance before turning to the Soviet Union. I think the US was already assisting the French at some level before they staged the false flag. I think there could have been multiple reasons for JFK's assassination including pay back for betraying the Bay of Pigs invasion. But I think the major reason was that JFK wanted to get the CIA back under constitutional control. I see the JFK assassination as a coup and Trump is attempting to get them back under proper constitutional authority. The confrontation with the FBI and justice department is just the beginning. The CIA and other intelligence agencies are next.
