To avert a possible catastrophe – this time set for February 2013 – scientists suggest confronting asteroid 2012 DA14 with either paint or big guns. The stickler is that time has long run out to build a spaceship to carry out the operation.
NASA's data shows the 60-meter asteroid, spotted by Spanish stargazers in February, will whistle by Earth in 11 months. Its trajectory will bring it within a hair’s breadth of our planet, raising fears of a possible collision.

My question is, How would painting it have helped? Maybe I didn't understand part of this plan...
Paint would affect the asteroid’s ability to reflect sunlight, changing its temperature and altering its spin. The asteroid would stalk off its current course, but this could also make the boulder even more dangerous when it comes back in 2056, Aleksandr Devaytkin, the head of the observatory in Russia’s Pulkovo, told Izvestia.

Come on now, it's 2012, why haven't we invented giant lazers to surround the earth and blast anything that comes close to smitherines? Come on scientists, hup hup, stop working on stupid weapons to bomb other countries, they won't really help if an asteroid knocks us into the ice age will it?
If the asteroid is as big as a 20-story building (200 feet on a side), it has an amount of energy equal to the largest nuclear bombs made today -- on the order of 25 to 50 megatons. An asteroid like this would flatten reinforced concrete buildings five miles from ground zero. It would completely destroy most major cities in the United States.
