I watched it Saturday night. Both me and the Mrs felt like we wasted 2 hours. No resolution, nothing but questions. Lame. Don’t watch movies or shows to have nothing but questions when they’re done.
That being said, they also only shot 2 missiles, had plenty of time for more. AND most of all. The policy of Mutually Assured Destruction is our main defense anyway.
I thought there was a possibility it was a phantom VR missile spawned by hackers. especially since it spontaneously erupted from the Pacific Ocean with no obvious country of origin. The fact that other countries were acting like a missile was headed toward them made me think that.
As one of the DC characters said, launching a single ICBM is national suicide. A true preemptive nuclear attack would involve the launch of hundreds of missiles.
