Recently news came out that a number of jihadists from IS have there dutch citizenship revoked.
however the government first needs to make a law to be able to do that, however theres one already.
it states that if you serve in a foreign country (When in war with them) you are punishable by law, seeing how those jihadists served as militia in the army of IS (and possibly other ones) they will fall under the regular law already, so why the bloody fuck do they need to make a law just for that? I see that as a failure in law.
