The Jews picked up a lot of their ideology from the Zoroastrians.
The Babylonians invaded Israel/Judea and the Jews were exiled.
The Persians took over Babylon and released the Jews. It was at this time the Abrahamics picked up concepts such as god/devil, heaven/hell etc.
If so, and the rural masses can get their own sons and daughters to work their lands like they used to (instead of relying on out of state labour), it might be a great thing societally for Panjab and Sikhs.
It's true, though a lot of people will disagree. Especially if you look at what Sikhs did in 47. Had the muslim population not been driven out then pubjab would of had a massive muslim population. This would of also attracted Muslims from other states like UP, and the mullahs would of definitely been inviting muslims from other states. and eventually Punjab would of become a Muslim majority state. Pakistan would of constantly got involved as well. It would been really bad for sikhs.
