Listen dumb ace, the way Iran is using cluster munitions on top of a platform set up or designed for multiple baby nukes to be deployed exactly in the way that the cluster munitions are being deployed, tells us that Iran was on it's way to develope nuclear weapons that can deploy in the same way that these clusters are being deployed.
If the clusters were nukes, then Iran would be eliminated immediately. In fact they will be eliminated because they are showing the world that they would go for total annihilation of many of their neighbor's and their enemies all due to their radical beliefs.
The world can't have a nuclear Iran, and that's that.
