The first end times war won't involve nukes. Just conventional. If Russia don't hand IRAN these toys to play with?
This war will start the hard times before the antichrist appears and offers a deal with ISRAEL to bind world PEACE. Which is just after the RAPTURE.
This war will just kill a few thousand people and damage a lot of property.
The NUKE wars happen after the first half of the tribulation. And, at Armagedon.
Nobody is CRAZY enough to turn Earth into a radioactive waste dump until EVIL is completely released through the evacuation of the Holy Spirit plus all believers. Until the Rapture, Evil will have binding enough to prevent a full scale world wide Nuke activation.
I think we will see major conventional war come to pass any time now though.
