We overran the launch sites and bombed the crap out of Peenemunde and Friedrichshafen, you pretentious wuss.
In any case: the V2 program was an expensive failure and a misallocation of materials that actually served to shorten the war in the Allies favour.
Seriously: you should open a history book instead of serially-masturbating in front of war-films.
As to accuracy, the V2 had a circular error probability (CEP), or target area, of 25 miles, making it essentially useless except as a terror weapon. By contrast, the Minuteman III ICBM's CEP is 200 yards.
