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 0.5-1 million band is honest uncertainty. Young Iranian infantry and Iraqi conscripts fill the lists; Halabja fills a civilian crime ledger.
Disabled survivors and unexploded munitions are a decades-long cost in both countries.

Iraq's main high-end sources in many categories.

Iraqi debt to Gulf creditors is a number that helps explain 1990.
Iranian martyr cemeteries are a built landscape of this cost.
