over modern cities would kill tens of millions of people.

How many nuclear bombs can destroy a city?

It would take just three nuclear warheads to destroy one of the 4,500 cities on Earth, meaning 13,500 bombs in total, which would leave 1,500 left. 15,000 warheads are the equivalent of 3 billions tons of TNT and 15x the energy of the Krakatoa volcano, the most powerful volcanic eruption ever.

What bomb can destroy a whole city?

A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy.

How much of an area can a nuclear bomb destroy?

The volume the weapon's energy spreads into varies as the cube of the distance, but the destroyed area varies at the square of the distance. Thus 1 bomb with a yield of 1 megaton would destroy 80 square miles. While 8 bombs, each with a yield of 125 kilotons, would destroy 160 square miles.

How can a nuclear bomb destroy a city?

Blast, thermal radiation, and prompt ionizing radiation cause significant destruction within seconds or minutes of a nuclear detonation. The delayed effects, such as radioactive fallout and other possible environmental effects, inflict damage over an extended period ranging from hours to years.

Irwin Redlener at Columbia University specialises in disaster preparedness and notes that there are six cities in the US that are more likely to be targeted in a nuclear attack – New York, Chicago, Houston, Los Angeles, San Francisco and Washington DC.

Can the US shoot down nukes?

To increase the probability of an intercept, the United States has to shoot multiple interceptors at each incoming ballistic missile. At present, because its inventory of interceptors is limited, the United States can shoot down only a handful of ballistic missiles that have relatively unsophisticated countermeasures.
