IMO......"stop" (destroy) a 1-5 mile wide solid chunk of nickle-iron ...not likely....
..but divert it just enough to miss the earth..
..depends on how much lead time we are given, how seriously we take the threat & how willing we are collectively to reach way into the hat (resources, nuclear & space assets, ect) to save our collective a $$es!
And retasking of space/ground based hardware & resources may give us the time needed to make a difference!
