Nuclear Physics, History, and Strategy
Listen to "Nuclear Physics, History, and Strategy"
Nuclear weapons, first created as a result of the Manhattan Project, come in many forms. The ones dropped on Japan, for example, were plutonium and uranium atomic bombs which used nuclear fission (breaking a larger nucleus into two smaller fragments). Hydrogen bombs, on the other hand, use nuclear fusion (fragments combined into a larger nucleus).
Over time, nuclear delivery also improved. Early on, only gravity bombs were used (ex. US bombers circulated around the USSR ready to drop gravity bombs). However, by the time of the Cuban Missile Crisis, rockets and ballistic missiles were developed to carry warheads. Submarine-launchable and backpack nukes also exist.
Because the power of nuclear technology is so great, a policy of Mutually Assured Destruction has been adopted. In other words, both sides don't launch nuclear weapons out of fear that the other side will launch their own.
Currently, there are seven countries known to possess nuclear weapons, and two who are thought to possess them.

This podcast contains at many errors:
1. The description of how a nuclear weapon works (a small explosive is started when the bomb hits the ground, a large amount of gunpowder launches a neutron down a tube). Nuclear weapons rarely are fused to explode at ground level - they are more effective as air bursts due to the strong P waves created. The bombs do not use "gunpowder", but rather very special high explosives (usually 2 types a fast and an a slow explosive), and they do not push a neutron down a tube - the explosives of nearly all weapons are designed to compress a sub-critical mass of uranium or plutonium.
2. The trinity test was not "dropped". It was contained in a shot tower.
3. The atomic cannon warhead does not have a blast radius larger than the range of the cannon. That would be stupid, and the video from the movie "Trinity and Beyond" clearly shows that the warhead will not obliterate the cannon.
4. The missiles in Cuba could not strike at the entire continental US except Seattle (I guess you also forgot Alaska).
