Iran effectively possesses relevant numbers of modern day jet fighters

I wouldn't worry in the least about this. Iran mainly has crappy planes, lack of spare parts and for their more advanced foreighn fighters and very likely bad pilots. NATO pilots require 180 hours per year to qualify for combat operations. That doesn't come cheap.

Most importantly however, Iran lacks an integrated air defence system. They do as far as I know neither have AEW nor any tactical data links, not until the Iran-140 AEW comes out in force. On top of that they will be flying into a veritable wall of electronic warfare. They'll be flying blind, and they will die.

I'd worry far more about mines, antiship missiles, fast attack craft and terrorist attacks.

Peak oil is not an energy crisis. It is a liquid fuel crisis.
