Is this necessarily true? Say there is tighter nuclear regulation being enacted in 2031, or nuclear material will run out in the 2030s, or it expects peace to happen in the 2030s? Would these situations not reduce the likelihood of Iran having a nuke? I would expect with all things being equal the likelihood going up over time, but external events may cause them to decrease more than they increase.

It doesn’t say “during 2040”, it says “before 2040″.
