Nothing outside of God himself will completely stop the jihadis, but these steps will considerably lessen the threat:
1) Ban Muslim immigration permanently, not just temporarily.
2) Deport the millions already here who have green cards, but arent yet citizens, back to their countries of origin.
3) Surveil the heck out of mosques and revoke the citizenship of anyone who has any ties to terrorism whatsoever, including members of CAIR and the other terrorist front orgs.
4) Destroy ISIS / the caliphate, thereby eliminating the most successful recruiting and emboldening tool at the enemy’s disposal.
Nuke Mecca and Medina.
