Gog and Magog...
Gog and Magog will make this largely irrelevant. All but 1/6 of the armies will be destroyed. Armies are largely made up of young men between the ages of 18-35. Iran, Libya, Turkey, Sudan, and Eastern European nations (in addition to Russia) are all mentioned. Syria is not. I think that is because the burden of Damascus happens first. Nevertheless, a lot of bad guys will be wiped out rather quickly.
