It’s perfectly legal for Dutch citizens to join the fight against ISIL.
Since late last year, members of the “No Surrender” biker gang have joined Kurdish forces battling the Islamic State of Iraq and the Levant. Klaas Otto, the leader of the group, has confirmed that at least three of the gang’s members were in Syria, according to The Daily Mail.
“Joining a foreign armed force was previously punishable, now it’s no longer forbidden,” public prosecutor spokesman Wim de Bruin told AFP.
However, to be clear, you can’t join a foreign force — i.e. ISIL — against the Netherlands.
The story of Dutch citizens wanting to fight against ISIL seems natural, according to The Daily Beast:

Then RT, Russian Television, fell in love with it. So did the British tabloids. And a New York one. And the story just keeps rolling.
Here’s a two-minute BBC interview with the leader of “No Surrender” explaining their involvement in the fight against the terrorist organization:
