Israel is widely understood to have 2 goals in its war with Iran: destroying Iran's nuclear program (primary) and regime change (secondary).
The market resolves to YES if either of the following are achieved by December 31, 2025:
Iran's nuclear weapons program is effectively ended, either via the destruction of nuclear sites/scientists or via a nuclear deal.
Iran's regime falls (e.g. in a revolution or military coup).
Some notes:
The first resolution condition is a bit vague, but I will resolve based on the consensus of reputable US and Israeli media whether or not Iran's nuclear weapons program is considered to be effectively nonexistent. One possible resolution would be a consensus that it will take at least a decade to rebuild the nuclear program to a pre-war capacity.
A change in leadership is not enough to resolve the second condition (e.g. death of ayatollah). It must be a change in regime.
Any nuclear deal that Israel views as insufficiently restraining Iran's ability to get a nuclear weapon (like the JCPOA) does not resolve to yes.
This market resolves whether the aims are achieved directly by Israel or not.
I disagree with the two goals.
For the first "primary" goal, it never had the ability to actual end Iran's nuclear program. That's widely reported. I consider this a multi step goal, the initial step being to get the usa dragged in to end the nuclear program for them.
If there's a new regime instantly in Iran that's stable, I don't think that's what Israel wants. It would rather a civil war with many factions and instability like what happened in Syria. Therefore it's not a regime change, It's an unstable Iran that doesn't pose a threat while Israel continues to weaken it.
I would add another goal, to stop Iran's ability to manufacture new ballistic missiles and try to damage the existing stockpile.
