Disarmament and A New Generation

[=sw=warlord]

Let me throw this out there: Global defense.

What happens if an aggressive alien species were to be introduced to our global theater of stupidity and petty squabbling? Wouldn't you rather the US & Russian governments band together and rise to the challenge of defending the mighty human race!? Against all odds, staving off annihilation at the hands of a voracious hoard!? Good God sirs, I challenge you to plan ahead; plan for the inevitable!

No but seriously, I think it'd be good to keep a large supply of nuclear weapons on hand. You never know.

If said alien species with interstellar technology were to somehow show up and decide they wanted us gone, what exactly makes you think we would have the technology to defend ourselves?
Seriously, if a alien horde were to show up knocking on our doors, then it would be obvious they would be vastly more technologically advanced than us, it would be like the Mongol throwing rocks and arrows at a challenger tank, just because nuclear weapons are the most destructive weapons we know off doesn't mean they are the be all end all and nothing can survive their use.
