Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many died?
About 500,000-1 million dead is the usual published band. Iranian military deaths are often put near the higher end of hundreds of thousands; Iraqi deaths are also in the hundreds of thousands. Precision is impossible.
Why did Iraq invade?
Border and Shatt claims, fear and opportunity after Iran's revolution, and Saddam's bid for Gulf primacy. Most historians treat it as an Iraqi decision, not an accident.
Did Iran become the invader?
After 1982, Iranian forces fought on Iraqi soil seeking a political end. That choice is central to debates inside Iran about whether the war should have stopped at the border.
Were chemical weapons used?
Yes. Documented Iraqi use against Iranian troops and against Kurdish civilians (Halabja). This is a historical and legal fact, not a technical discussion.
How did it end?
Iran accepted 598 in 1988 after military setbacks and isolation. A UN-monitored ceasefire followed. Neither side achieved its maximal aims.
The first campaign was a grab for Khuzestan. The long campaign was a siege of Basra that never quite became a fall of Baghdad.
Faw (1986-88) was a peninsula with outsized political weight -- access and prestige.
Principles
Stopping at the border is a decision
Iran's 1982 choice lengthened the war.
Isolation is a strategy against you
Iran's diplomatic loneliness mattered as much as any trench.
Crimes do not stay local
Halabja entered later international law stories.
A UN text can end a war without ending politics
598 as a ceasefire, not a friendship.
Steps
- Gamble
September 1980 invasion.
Opportunity plus grievance is still a choice.
- Failed knockout
1980-81: Iran holds.
Short-war scripts die in winter.
- Reversal and temptation
1982 liberation, then advance into Iraq.
Success creates a new aim.
- International fronts
Tankers and cities, mid-1980s.
A land war grows extra domains.
- Crime and isolation
Chemicals; Iran's loneliness.
Means can stain the end-state.
- Poisoned cup
598 accepted; 20 August 1988.
Ending can feel like defeat to both.
Diagrams
Land (Shatt/Basra), cities (missiles), sea (tankers).
Vote, Iraqi accept, Iranian accept, ceasefire -- a diplomatic sequence.
Limits
Casualty politics
Both states still police the numbers.
Archive gaps
Iraqi and Iranian files remain unevenly open.
No how-to
No employment or manufacturing detail for weapons used.
Missile and tanker sequences are historical. They are not targeting instruction.
The war of the cities showed that reach against civilians did not break either regime.
