Tractor beams pah!
Why not simply build an antimatter cannon, this would obliterate the NEO in a lovely big explosion full of booms and whooshes with an accompanying fireball and finally a white fwoooooooom with a ring of light that will shoot out across the solar system.
CERN could supply an almost endless amount of antimatter material and I'm sure the merkins have some sort of laser cannon that could be modded by er lets say Mr T and the rest of the A team.
If that fails all we need to do is shift the earth out of the way by getting all the cars in the world to accelerate the same way at the same time thus pushing the earth slightly away from the sun. Sorting out global warming! and saving everyone!
Of course while this is going on the team in charge of all of this needs 1 old but experienced engineer with a hot genius daughter, a young muscular physicist to fall in love with said daughter, lose in a misunderstanding and then ultimately win back . A weasely officer who gets killed but only after redeeming himself oh and the token black guy.
Ah and right at the end the politician who didn't want them to go puts a gun in his mouth /gets fired/ gets squashed by the only piece of NEO to make it through (depending on the rating and comedy value needed)
Or we could do something else.
