You really shouldn't talk on matters you have no knowledge of. It only goes to re-affirm your own stupidity. Time for some education.
1. Wahhabism is not extremism or terrorism. It is a puritanical revision on Islam, a different creed of the same religion all of us follow. The difference is in something we call Aqeedah.
2. Wahhabism has been spread using an evangelical approach and oil money all over the world. The model was to spend money to train imams, print free books, spread them to the public and fund mosques. From the perspective of the Saudis, they're doing God's work, it's missionary work.
3. The same methods mentioned in part 2 are used in the USA, UK, Canada, EU etc as well as Asia and Africa. Even in India.
4. Wahhabism has very little footprint in our part of the world where the Deobandi and Barelvi revisionist groups are dominant. They were at thier academic height at the same time Wahhabism was emerging and taking flight. They both rejected aspects ofthe wahhabi aqeedah as flawed as well as making the same accusations about each other.
5. The vast majority of terrorism faced in Pakistan has been by debandis. The vast majority of anti blasphemy extremism by barelvis.
6. Saudi money does fund extremist groups. Its often channelled in the same was missionary money is.
