This chapter deals with the viability of national public commissions being used as a policy tool, by governments or private institutions that seek to address national issues of cultural and religious diversity. It aims to help governments to avoid past mistakes and it also provides examples of how to improve national public or private commissions in the future. Through their respective critical lenses, several authors directly address, both ideologically and praxically, how to respond to increasingly diverse national societies, especially along cultural and religious lines, and how to handle public discussion. Recently, the exponential growth in counter-violent extremism (CVE) programmes, also known as 'deradicalization', raises important and urgent questions about how to manage religious diversity in particular, before various forms of exclusion end up dividing diverse national communities into segmented groups along falsely perceived identity lines.
