Please be warned the criteria for this are very subjective and may be controversial.

I will use my own judgement to decide if AI has started a war. If an AI convinces someone to launch a missile or fire a gun and it starts a war this will resolve yes. AI spreading misinformation that starts a war will also resolve yes. If AI is only used as a tool in war and doesn’t start it it will resolve no. If there is no consensus in 2040 the close date will be extended.
