nuclear war

[Mortblanc]

You have not googled "nuclear bomb" yet have you Paul?

You are not dealing with a single conventional artillery shell, you are talking about multiple nuclear weapons that destroy a 5-10 miles target area at ground zero, flatten and burn everything for the surrounding 50 miles, and radiate everything for miles around. The radiation waste then spreads for hundreds of miles in the air currents, usually west to east.

The Russian weapons are not very accurate so don't count on being safe if outside a city. They might miss. It also means that they plan to send multiple warhead devices and take out whole regions rather than just one small village.

A series of 10 nukes along your west coast, plus one on each major city, would turn your entire island into a nuclear exclusion zone for about 25,000 years.

The Chernobyl exclusion zone is as large as Kent, and it was not a bomb, just a set place industrial disaster.
