and on a side note... w00t! Russia won! look at my name
Actually in the second video, from the looks of it, N.A. fired its silo nukes then shortly after this a nuke detonated in southern Japan (likely a N.A. Sub?). Following these two events South East Asia and Eurasia fired mostly at eachother(!) as well as sending nukes towards N.A.
It also seemed like a lot of the initial nukes fired at N.A. were intercepted, did the N.A. Silos have time to switch back to defense mode or was I just not seeing things right.
