This was actually successfully done. I'm having trouble finding the article, but basically a terrorist group (perhaps in Palestine) had trained some men specifically to be some of their most dedicated and zealous terrorists. However, the situation changed and they found that they no longer needed these zealots and had no idea what to do with them. So they held a mixer where the terrorists got to meet potential brides, and basically said that if they promised to live a normal life, they'd receive some financial compensation to get started on that normal life. All of the trainees ended up getting married and having families, and lost all desire to commit terrorist acts.
