Don’t forget...
JFK screwed up Cuba and the Bay of Pigs, sending that nation into Hell for the past 60 years.
JFK sent troops into Vietnam, escalating that into a war.
The Bay of Pigs was as much on Ike. Kennedy certainly signed off on it, but it was already set up.
Now Kennedy did approve the assassination if Diem. So compare that to Trump blowing up a general.
