I need to dig into this. Various commentators indicate this was the war in 2 Chronicles 20.
Thanks for your post - I need to study 2 Chronicles 20 more. A brief perusing of it suggests that is past - but it’s always good to study the Scripture itself and let the Holy Spirit guide.
There is another prophecy (future) regarding Western Iran in Jeremiah 49:34-39. It reads like a nuclear incident or attack and interestingly enough, that is where Iran houses the bulk of their nuclear technology/weaponry.
