aaronI'll share a troubling fact with you if you share one with me
If a nuclear missile is launched at the United States the President has just 6 minutes to come to terms with that and decide to launch a counter attack.
If that counter attack is headed to North Korea, any land based missiles will head over the arctic circle, over Russian airspace where similar shoot/no shoot decisions will have to be made.
That is why subs with nukes are hidding someplace. If the president is wrong and now the us doesn't exist the captan will finish ending the world
r00tyMost nuclear enabled countries have nuclear subs. I believe here in the UK our entire nuclear deterrent is based on trident missiles fired from submarines.
You are probably right, russia is just the only other country I'm sure of.
