In the 34 months John F. Kennedy was president:

1) we entered Vietnam in force;
2) relations with the USSR dipped, and the Berlin Wall was built;
3) covert actions to depose of Fidel Castro backfired, and the Bay of Pigs disaster occurred;
4) the number of nuclear ICBMs was increased from 63 to 424 (the "Bomb" era was now on us);
5) his Secretary of Defense (Robert McNamara) agreed to various defense sweetheart deals, one of which being the infamous M-16 rifle (fielded too early, resulting in battlefield deaths);
6) created the Food Stamp program (which is still a mess); and
7) brought nepotism to new heights with the appointment of his brother as Attorney General.

Yep, he did "accomplish" more in his 34 months than Pres. Bush did in eight years...
