Why is Steins;Gate in the Beta Attractor Field? As stated in the Wiki, the Steins;Gate world line is in 


   the Beta attractor field. In the Beta attractor field, the final convergent point is World War 3.


However, they prevent


   WW3 by making sure the thesis will be destroyed.


The question is, if Steins Gate is in 


   the Beta attractor field, wouldn't it lead to WW3? If WW3 doesn't happen, shouldn't Steins;Gate be in another attractor field?
The Steins;Gate World Line is not in the Beta Attractor Field.

While the final result of the Beta Attractor Field (World Lines 1% to 1.99%) convergence is WW3 which is fought over Makise Kurisu's time travel thesis, Steins;Gate (1.048596%) is the only exception because the thesis is destroyed (and thus time travel doesn't exist in that World Line).

At the beginning of the final chapter of the VN and episode 23 of the anime, Suzuha herself had told Okabe that the Steins;Gate World Line is not bounded by any attractor field.
