The only interesting aspect of this - is how much attention this event is getting in the press, and on this site. This asteroid was discovered in 2002, the close approach was predicted for 18 years, it has long been understood that it will not hit Earth, and a dozen objects have come closer to the Earth in recent months. This story is like a toddler looking in the sky, seeing an airplane, and yelling to the room that the plane might 'hit us!'. Please please don't spread these bullshit stories.
It must be ~50 years since any world leader observed a nuclear weapons test. I wonder how many have even watched the films. It has even been 36 years since the movie "The Day After" was shown. The people who might take us to nuclear war have less idea of the effects than you have for watching this short video. https://en.wikipedia.org/wiki/The_Day_After
Nuclear annihilation ... Sarah Palin.
Sort of a toss-up.
