The Russians are good fighters but remember Afghanistan. They weren’t used to the shoot-them-dead-right-where-you-find-them policy. On Russian soil it may be different, though.
Yes, Gog and Magog. That’s to come. Iran and Russia is the common interpretation.
Note that for Gog and Magog to happen, Russia has to survive. Some of the players disappear from prophecy after a certain point, which probably means they were vanquished in a previous scenario.
What’s likely to happen here is that the sheer force will bring the ISIS down, but ISIS will take down a whole lot of people with them, via collateral damage. Given the capacity of a militant to infiltrate a mainstream society posing as a regular joe, well, that means that some damaging effects such as a “repeat 9/11” event may very well happen in numerous nations.
The Russians were winning in Afghanistan until the US started supplying the Afghans with Stinger missiles to counter the helicopter gunships.
The Russians were quite willing to shoot them dead right where they found them.
