Dr. Leuprecht, do you have anything to add?
Then moving to your larger tool kit, I think, Dr. Leuprecht, in your remarks—and maybe you didn't intend it this way—but I wondered whether you had confidence in deradicalization programs.
I ask because I think Mr. Quiggin is right. I think this is one measure that's needed among many. Young people of 18 are wanting to leave—some of them are wanting to leave for just pure adventure I expect—and they are having their passports revoked. But I hope that there are ways and means for them to get their passport back, as things change over time and your life experiences change.
Should deradicalization programs or other programs be necessary to accommodate that? You spoke about that a little earlier.
