The changing nature of warfare and international conflict, 1919–2011 · Option B6 · Paper 2 Section B — breadth study in change

Key topic 4 · Conventional war and the development of 'new' wars, 1976–2000

What a Grade 9 answer knows here. The USSR in Afghanistan and the USA in Vietnam lost the same war twice: a superpower with total firepower superiority defeated by an opponent who only had to avoid losing. That symmetry is the strongest comparison in the option.

Every lesson here ends the same way: learn it, teach it to an AI pupil who asks the awkward question, then defend it against the thinker with the strongest claim on it — free · no account needed.

2 lessons, each answering one essential question with the story, the dates that earn marks, the people to place, how historians disagree and the cap in the mark scheme that bites. Completely free.

The 2 lessons

The first Gulf War, the Falklands and carrier warfare

Did air power win the Gulf War in 1991, or did it make the ground war short? Argentina occupied the Falkland Islands in April 1982 and Britain assembled a task force to retake them 8,000 miles away, with no land air base within range.

Afghanistan, 'Star Wars' and the end of the arms race

Why did the same kind of war defeat both superpowers within fifteen years of each other? Soviet forces entered Afghanistan in December 1979 to support a communist government against an insurgency, and withdrew in February 1989 having failed to defeat it.

The dates that earn marks in this key topic

Two from each lesson, in the order the topic is taught — each with the reason it is worth a mark, and the lesson that places it.

2 May 1982 — HMS Conqueror sinks the General Belgrano; the Argentine surface fleet returns to port.
It shows a nuclear submarine removing a navy from a campaign by threat rather than by sustained attrition. (The first Gulf War, the Falklands and carrier warfare)
4 May 1982 — HMS Sheffield is hit by an Exocet missile.
It is the moment the anti-ship missile's threat to surface fleets became undeniable, and it reshaped naval air-defence procurement. (The first Gulf War, the Falklands and carrier warfare)
December 1979 — Soviet forces enter Afghanistan.
It begins the nine-year commitment whose failure supplies the Vietnam parallel and the pressure on the Soviet system. (Afghanistan, 'Star Wars' and the end of the arms race)
March 1983 — The Strategic Defense Initiative is announced.
It challenges the logic of the ABM Treaty and therefore the stability of deterrence, which is why it dominated the arms talks that followed. (Afghanistan, 'Star Wars' and the end of the arms race)

What the specification asks for

The clauses of 4HI1 this key topic examines, one per lesson. Incandio is aligned to the specification and is not published by Pearson.

Then teach it, and defend it

Every lesson above ends the same way: you explain the argument to Ember, an AI pupil who asks the awkward question, and defend it in a structured debate marked against published descriptors.
