An ICBM won't cut it... a single nuke won't cut it... So, can we get in short order a dozen or so space capable rockets that are nuclear tipped with a large enough payload to make a difference? Cold-war theories would say yes due to the arms race and all that jazz... I think not.

I agree with you. And yes, I mean something we have ready or can have ready in the next 1 to 5 years.

Any other technology we have, is unproven.

Heh, I don't think you realize just how much destruction we can unleash if we want to. Yeah, the actual action would be unproven, but the math is proven. That math would state if you setup a blast of X power in X location it would alter the heading of an object of X mass and X velocity my a degree of X. The only way it would be impossible was if we couldn't make a blast powerful enough...or get it on target. However, it doesn't take much to change the direction of a moving mass...look at little tug boats pushing giant ships around.

That is because right now the only goal is to get money and power...and status on the global scene.

I have a feeling that if we were faced with this...stuff would happen quite quickly. That is the only time when humans will ever work together is when faced with great adversity. I honestly wish it would actually happen...because I have the very firm belief that humans would prevail...and right now the global scene could use a common goal for every one to work towards. We could survive unscathed and emerge as a stronger more productive species...or die. Give those choices I think I know what people would pick...though I also have no doubt that about six months after the fact we would revert back to our selfish ways.

We have much of our difficulties in using or adapting older technology. What we're discussing here can relatively easily be adapted from current technologies (especially seeing as there is no need to send people on these missions).

Also, I think you're overestimating the large objects in our vicinity that have a relatively high chance to hit us. If you'll notice, these world changing events are exceedingly rare, occurring on the scale of once every several million years. And if we want to get technical on things that might happen, then we also have to take into account the chance of things like cosmic ray bursts that noting could ever possibly survive by any means.

I really hope you are right, although we are talking about something even the smartest people on earth don't fully understand. Space is a sophisticated subject and anything can happen. I hope by the time we are faced with such a disaster, we (or rather future generations) are well prepared.

deflecting an asteroid is not magic nor impossible. there are several viable methods with current tech, some as simple as spray painting part of the asteroid, we just need the motivation to build/test actual systems... I am 100% positive that if we see an asteroid coming at us we will find our motivation is not lacking anymore.

huh? what exactly about Space (related to deflecting a NEO) even the smartest don't understand?

Then after I got off work, I was watching the news and learned what I saw was in fact the asteroid!

I honestly wouldn't mind if a large asteroid hit the earth. Given our advanced technology its unlikely that an asteroid impact even of the same magnitude as the K-T even would wipe us out (after all, our furry little ancestors survived the last time).

It would wipe out a large percent of the worlds population though, which is going to happen within the next 100 years anyway. Its either asteroid impact killing everyone off within a year or two, or 50 years of widespread famine and suffering thanks to topsoil erosion from overfarming. Even though I live in a sparsely populated, developed country that would likely come out ahead in the latter (assuming our violent neighbors to the south don't try and annex us again) I'd rather risk the asteroid. Death by giant flying space rock is at the top of my list of ways to die.

uh, no. you most likely saw something else. shooting stars are inside the atmosphere and are not asteroids. this asteroid passed us at a quarter million kilometers from earth.
