Given the advisers and military hawks surrounding Ike and JFK, it's a miracle we made it through the end of the 60s.
They couldn't intimidate Ike like they could JFK because Eisenhower had so much experience at the highest levels of the military. And Kennedy held them off pretty well, especially in the Missile Crisis, when they were all hot to invade Cuba, but he missed the best chance to get us out of Vietnam in 1963 with minimal damage because he was more interested in getting re-elected than making the hard, right but potentially unpopular decision to withdraw completely.
