A real pros/cons situation
Pros for preemptive strike - potentially saves millions of your countrymen
Cons - starts WWIII, with the only excuse being a technical, poor one
Pros for holding back - avoiding WWIII
Cons - crushing guilt over not firing first if indeed they launch
There's no question really. You'd always prefer the guilt of not launching over the guilt of starting a nuclear war, but if you were out there, thinking of loved ones - well I could definitely suspend disbelief. Not an easy team to support though, when your commanding officers are Hackman, superb as a bully, and a sneering James Gandolfini.
