Could a Nuclear Weapon Level New York City?

A 300‑kiloton warhead detonated at 2.4 km altitude would devastate NYC:

• Blast wave: Destroys buildings within several km; collapses high‑rises; shatters windows far beyond.
• Thermal radiation: Ignites widespread fires in dense urban fabric.
• Fallout: Radioactive contamination of water, food, structures; long‑term cancer risks.
• EMP: Disables electronics, power, communications, transport, hospitals.
• Casualties: Extremely high due to density; immediate deaths plus radiation sickness.
• Long‑term: Large areas uninhabitable; recovery decades or generations.

Exact effects depend on yield, location, weather, preparedness—but a single weapon can cause catastrophic consequences.
