Unfortunately, according to the B612 Foundation, an atomic blast could easily fracture the asteroid, resulting in thousands of illegitimate baby asteroids bombarding the planet like global buckshot. Instead, the B612 scientific group--helmed by former astronaut Rusty Schweickart--wants to use some high-level scientific spells to gently bump or tow all dangerous space dirt away from us. The problem is that the aiming process would temporarily point it at places in the so called "risk corridor."
Also known as the "f**k You Line."
Yes, they've proposed a path that would cause the least amount of damage, which the scientists admit is a real "f**k you" to the many millions of people that the plan requires to sit tight while they pass beneath the sites of a rapidly approaching asteroid. A hit along that Equator of Expendables, which includes Russia and Venezuela, might result in the least amount of damage (chances are you're not getting international approval without a few wars).
Schweickart presented the group's theories at the American Geophysical Union in December 2009, and his proposal will probably soon land in front of some UN delegates. Maybe they'll be able to decide who gets to take one for the team: the vast, empty plains of Siberia or the home-country of Stefania Fernandez.
Russia who now?
