I'd recommend a closer look at the Northern Ireland situation, where it is commonly agreed jailing terrorists had a remarkable political impact and there was more pressure from prisoners on the political process than those outside exercised. Similar effect in South Africa. Indeed there is traffic in expertise between the two since peace.

Less well known here (in the UK) is the experience in Italy, with the Red Brigades and Spain, with ETA.

From a different angle the study of women suicide bombers held in Israeli jails has some lessons, best source I can readily find is:
