The agreement proves not enough.
Sanctions relief stabilizes the economy of Azmenistan, but with its nuclear equipment already in place, two years later Azmenistan 'breaks out' and begins highly enriching uranium and racing toward a bomb.
Now likely just six months or so from producing its first nuclear weapon, Azmenistan will be even harder to stop. It looks like you will need to begin again. At least you learned some lessons from the first time around!
