can white prevent this pawn storm blockade ?

"one usually wants to play agressive in the english attack "

• This is naive.
  Capablanca: an attack can only succeed if you control 2 or 3 of the central squares e4-d4-e5-d5.
  In this case white occupies and controls e4.
  Black occupies and controls e5.
  Black controls d4 from the pawn at e5: white cannot put his knight there.
  Square d5 is contested. Black cannot push ...d5, but white cannot put an outpost Nd5 into the hole at d5.
  The point of 11 g4, 12 g5 is not to checkmate the black king, but to drive Nf6 away from the defense of d5.
  Black thus played 13...Nb6 so his other knight defends d5.

I thought that queenside castling is usually more agressive than kingside because white pawnstorms the king , if this is not or not primarly the goal then what are the differences between queenside , kingside castling ?

"I thought that queenside castling is usually more agressive than kingside"

• Yes, it is sharper.

"what are the differences between queenside , kingside castling ?"

• What you say is true, but the attack is only possible if you control the center.
  In the regular Sicilian with ...e6 white has his central knight on d4 that supports the attack.
  With ...e5 black kicks the knight from its central position on d4 to the poor square b3, but at the cost of accepting a backward pawn on d6 and a hole on d5.

if you say it is true that the goal is pawnstorming and a normal center attack then why did you say g5 is for kicking the knight and not for attempting to checkmate by a pawnstorm

"g5 is for kicking the knight and not for attempting to checkmate by a pawnstorm"

• In the regular Sicilian with ...e6, like the Keres Attack against the Scheveningen Variation, white controls e4 with his pawn and d4 with his centralized knight, that gives an attack.
  In the Najdorf Sicilian with ...e5, black has kicked Nd4 out of the center with ...e5.
