You're right that they're important for maintaining the balance of power at the moment. They have helped maintain relative peace. My point was that on a long enough timescale mutually assured destruction won't hold up as a deterrent. It's too short sighted a solution. What happens a few hundred years from now when the current political powers have waned? Could Russia and the US still safeguard their nukes if faced with a civil war? Would they have the restraint not to resort to them if they were invaded by a superior conventional army? Political boundries shift, just because there's a enough of a balance to prevent war now doesn't mean that will always be the case.
some say it would of been better if the united states never invented the nuke, but where would we be without them, would japan have taken over?
To be perfectly honest in a world without nukes I'd be more worried about the USA than anyone else. You might not be the craziest nutters around, but you're the ones with the biggest guns.
FYI, sharks have been around closer to 500-600 million.
Thanks. I had a hard time pinning down the origin of "modern" sharks, but you're right ancient sharks were around much longer.
