So you believe these very powerful forces (FBI, CIA, Pentagon, Justice) that murdered JFK - and framed Oswald and then covered their tracks - didn't have the ability and resources to frame JFK for something? Their only course was to shoot him in broad daylight in the middle of a crowded street and then frame someone for it? Then cover all of this up?
This is what is odd about the conspiracy claims: these forces can do anything but yet are quite limited at the same time.
BTW: LBJ "escalated" US involvement because the North's attacks on the South increased. The South, after Diem's death, was increasingly incapable of defending itself from the North's increased activity. LBJ was faced with the problem of either abandoning the South to the North or trying to prevent that by increasing the US role. The South simply couldn't do it by themselves.
Easier said than done.
What could they have Framed Kennedy with? Something illegal? A Sex Scandal?
I doubt they would've been able to get Kennedy to unwittingly commit a crime. Plus his brother was the Attorney General. Good luck with that.
A sex scandal? Not in the 60s. The Press was different back then. The News media greatly ignored the womanizing and sexual escapades of Presidents in that time. Kennedy and Johnson did stuff in the White House that would make Bill Clinton's Lewinsky scandal look Rated PG.
I don't think using violence to remove politicians and heads of state is Easy relative to other options but in the 50s and 60s a number of politicians and heads of state were violently removed from office. People viewed assassinaton as an effective way to accomplish regime change.
I'm not endorsing the idea that Kennedy's murder was an inside job. Just saying if you really think about it, removing a popular head of state from office via non-violent conspiracies or elections is very difficult...
