Questions from this subtopic

Each one with the model answer underneath.

1. 1

   Define weapons of mass destruction.

   Model answer

   Weapons of mass destruction are designed to kill very large numbers of people at once. Nuclear, chemical, biological and radiological weapons fall into the category.

2. 2

   Define nuclear deterrence.

   Model answer

   Nuclear deterrence is keeping nuclear weapons so that an enemy is afraid to attack. Safety comes from the threat rather than from any use of the weapons.

3. 3

   When were nuclear weapons used in war?

   Model answer

   The United States dropped atomic bombs on Hiroshima on 6 August 1945 and on Nagasaki on 9 August 1945. Tens of thousands of people died immediately in each city.

4. 4

   What is the UK's nuclear weapons system called?

   Model answer

   Trident is the UK's nuclear weapons system, carried on submarines. At least one submarine is on patrol at all times.

5. 5

   Give one argument in favour of nuclear deterrence.

   Model answer

   Supporters argue that no nuclear-armed state has been invaded by another. The threat of retaliation has kept major powers from direct war.

6. 6

   Give one argument against nuclear deterrence.

   Model answer

   Deterrence works only while the threat is believed, so a state must be willing to use the weapons. Accidents, miscalculation and theft all remain possible.
