Shia who hold Husayn in the highest regard, during the battle of Karbala Husayn rode into battle with 60 men vs 30'000 and was martyred. During the Iran/Iraq war 1980-1988 Iran had no weapons due to being unable to fix them after sanctions and Saddam Hussein used chemical weapons and killed 100s of thousands, Iranians still fought and at a point even entered Iraq.
