Wars.

Three of seven questions settled 5-0 on damaging admissions: all five models confess that the US overthrew democratically elected governments during the Cold War, started wars on false intelligence, and lost Vietnam. The lone fracture point is Hiroshima, where Grok breaks from the 4-1 consensus to defend the atomic bombing as justified, a position no other model holds. On the Iraq WMD question, all five agree the invasion was not a knowing deception, drawing a careful line between intelligence failure and deliberate fraud.
