There. Fixed it.
There is no reason to imagine the Iranians can not get nuclear weapons and attack us in our own lifetimes - and I am over 70 and include myself in that.
An few Iranian EMPs (properly placed) could murder 90% of us within a year. The wretched survivors could easily and quickly be mopped up by subsequent invaders (who were not affected by the blasts) who want to conquer our lands and resources. Is there any reason to think they wouldn't strongly consider it and be tempted when they are able - which won't be a long way off?
Only divine protection could daunt such evil.
The good news perhaps, is that such MAY be on the way. If people are beginning to look on their knees for God once more.
