No he didn't. The war JFK was in was with the CIA. The Clowns In America wanted war in VietNam and in Cuba (and later, Afghanistan)... the CIA is all about war (Eisenhower's warning about the Mil Ind Complex included the CIA).
JFK famously said he wanted to shred the CIA into a 1000 pieces and scatter into the winds.
JFK also was opposed to the FED, in EO 11110, creating silver treasury dollars.
LBJ cancelled and reversed all the good things JFK did.
The president is in charge of the military not the CIA. Kennedy was responsible for the deaths of about 50k Americans. If he didn’t want us there we wouldn’t have been. Democrats all suck.
Yup, that is what Ike was warning g us about.
