Re: But Really...
It's basically a re-run of the Cold War, but instead of mutually assured nuclear destruction we have mutually assured economic destruction and instead of the two sides being openly hostile towards each other they're actually business partners and largely dependant on each other.
That It's also completely insane is par for the course.
Here's the kicker though, because the consequence of lobbing a nuke were very well understood by all sides to almost certainly result in the end of all life on earth, a whole bunch of systems and safeguards were implemented to ensure that it would be really hard to either accidentally fire one off or for some guy to have a bad day and decide to fuck the planet. Wasn't perfect of course and the fact that we're all still here is completly down to the fact that on the occasions the system failed the guys that were told to press the button didn't.
This time round there's no safeguards, if one guy hacks into the right system and decides wipe it for the lols instead of pwning it for God and Country, it could escalate shockingly quickly to a couple of billion people surprised by the sudden loss of power, communications and water.
