It is 2025. Soviet missiles are no longer the most advanced technology and it's not impossible to imagine that Iran has developed technology better than that of a country that hasn't existed for 25 years.
There is much evidence supporting Iran as having missiles capable of maneuvering post launch.
Thats why they aren't just comparing each state just to the US average but to other countries.
There are 35/50 states on the graph, with 34 of them above the 2nd highest country (el Salvador).
This shows that even the US states that are lower than average are still higher than other countries.
